1. Silicone Roof Coat – Restore, Seal, Adhere – 1 Quart
I recently used this product to seal some leaks on my shed and I am extremely satisfied with the results. The application process was easy and straightforward, and so far, the leaks have been completely fixed. I am confident that this product will provide long-lasting protection for my shed.
I also had the opportunity to use this product on a used fiberglass truck topper that had lost much of its gelcoat. I was initially skeptical about whether it would be effective, but the affordable price and availability in smaller quantities convinced me to give it a try. I am thrilled to say that it worked beyond my expectations. I applied it to the top of my truck cap and have not experienced any seepage or leaking since. In fact, I am considering ordering more to re-coat the top of my 20+ year old RV.
I found the product to be of high quality and easy to work with. It has a fairly thick consistency, but I had no trouble applying it to my 21-foot travel trailer. The end result was a significant improvement and a solid, waterproof surface. The product also dries fairly quickly, which was a bonus when unexpected rain occurred the following day.
One of the standout features of this product is its versatility. I found it to be easy to apply with a paintbrush, and it adheres well to all prepared and dry surfaces. It is completely waterproof and remains flexible without cracking. I used it on my gutters and the results were excellent. It provided a reliable seal and gave me peace of mind knowing that my gutters were protected.
Lastly, I used this product on my metal roof to address leaks around screws and seams. The results were truly amazing. The product effectively stopped the leaks, and I highly recommend it to anyone in need of a reliable solution for roof leaks.
2. Roof Restore: 100% Silicone Coating – Leak-Seal Solution
I recently used the Countryman roof coating on my flat roof and I must say, I am extremely pleased with the results. The application process was a breeze, as I was able to use a 1/2" nap roller straight out of the can. The product claims to have a high solids content, which supposedly helps keep more of the material on the surface after curing. I haven't come across such a claim from GACO's silicone product, but if anyone has more information on this, I would appreciate it.
In terms of coverage, the Countryman roof coating performed exceptionally well. I applied it on my 465 sq ft flat roof, which had a cap sheet roofing material. The product covered the surface nicely and when it dried, it looked great. However, I did find that it required some effort to transfer the product from a 3/4" roller to the roof. I had to frequently re-dip the roller, but surprisingly, the product went much farther than I expected. This left me with plenty of coating to go back and touch up the edges. It was definitely a much more cost-effective solution compared to replacing the roofing material.
I also used this roof coating as a recoat over a Henry silicone roof coating on an old EPDM roof. It worked very well for me and I am satisfied with the results. The final outcome was even better than I expected, as my RV roof now looks better than new. If you don't believe me, I have before and after pictures to prove it!
3. Henry He887hs073 Tropicool5gal Tropicool Roof Coat, 5 Gallon
I have been working as a mobile RV tech for quite some time now, and roof paint jobs are a regular part of my work. Over the past few months, I have experimented with different paints, including the popular ones like Hengs and Dicor. While they did the job well enough, I found that they required multiple coats for full coverage, which was time-consuming.
However, my search for an efficient and effective paint led me to Henry's 887, and I must say, I am extremely satisfied with the results. After power washing the RV roof, applying this paint was a breeze. The consistency of the paint is thick, almost like Elmer's glue, which ensures excellent coverage. Surprisingly, I only needed about 1.5 gallons for a 25-foot travel trailer, despite its thickness.
The color of the paint is a clean white, which not only looks great but also helps in reflecting the sun's rays on hot days. To ensure a thorough application, I recommend using a long bristle paint brush for hard-to-reach areas like under the AC and around the vents, and a small roller with a shield for the rain rail seam. With these tools and some practice, I have been able to complete an average trailer in just 4 hours, including power washing and prep work.
What truly impressed me about Henry's 887 is its performance. The paint goes on thick and provides a protective layer on the roof. Despite an unexpected change in weather during one of my applications, where the sun suddenly came out and the temperature rose significantly, the paint still held up well. It may not have been as smooth as I had hoped, but it did the job.
One of the main reasons I chose to try this paint was to address leaks on the roof of a car hauler. I am happy to report that the leaks have completely stopped. Additionally, the interior of the trailer used to become unbearably hot due to the sun's heat, even with fans running. However, after applying Henry's 887, the temperature inside has significantly reduced. On a scorching day with an outside temperature of 101 degrees, I can touch the roof without getting burned. The TropiCool coating has provided excellent insulation, and I can confidently say that it has reduced the interior heating by 15-30 degrees.
While I would have liked to provide visual evidence of the roof coating, a picture doesn't do justice to the effectiveness of the product. It is simply a sea of white, and a picture would not add much value. However, I am considering using an IR thermometer to showcase the temperature difference before and after the application.
4. Liquid Rubber Waterproofing And Protective Coating – Roll On White (1 Gallon, White)
I recently purchased the RubberSeal Liquid Rubber Waterproofing and Protective Coating for my 1994 19' Starcraft camper trailer, and I must say, I am extremely satisfied with the results. After researching various options such as FlexSeal and Rust Oleum LeakSeal, I stumbled upon this product with excellent reviews and decided to give it a try.
Firstly, the pricing and packaging of the product were satisfactory. I purchased a gallon of the white coating, and when compared to other similar products in the market, the price was competitive. The product arrived securely padded inside a box, which was then placed inside another Amazon box, ensuring its safe delivery.
The application process was straightforward. I used a paintbrush for the first coat to ensure a thick and even application. After 24 hours, I applied a second coat using a 6" mini roller. While I applied the coating inside my garage, I would recommend waiting for a few days of sun before applying it. Surprisingly, I did not clean the roof before application, as it was already relatively clean.
I found that one coat of the RubberSeal did not provide sufficient coverage, but the second coat did the job well enough. In fact, I still have half a gallon left, so I might even apply a third coat for added protection. The sealant effectively penetrated all the cracks and seams of the roof, providing a secure bond. It seems to have sealed right over the areas where the metal meets the vents, and I cannot scratch or chip it off with my nails.
Cleanup was hassle-free for me as I disposed of the paintbrush and roller cover. However, the product recommends using mineral spirits or baby oil for cleanup. Unfortunately, I did not have either of these on hand, and alternatives such as gasoline and paint thinner did not work.
As of now, I am highly satisfied with the RubberSeal Liquid Rubber Waterproofing and Protective Coating and would recommend it to fellow RV enthusiasts. If I don't provide an update to this review, assume that my satisfaction remains at 100%.
In addition to my review, I would like to address some common complaints I have come across. Firstly, it is crucial to read the directions before starting the application process. Cleaning the surface thoroughly is essential to ensure proper adhesion. Multiple coats are recommended for maximum protection, so those who claim it doesn't work might not have followed the instructions correctly.
I have personally had this coating on my RV roof for two years now, and I frequently walk on it to sweep and remove debris. Even with objects falling on it, I have encountered no problems. I applied 14 coats, using a 5-gallon bucket for my 26 ft. travel trailer. While it may go on thin, the directions explicitly state the need for multiple coats. I have washed my roof four times with a scrub brush on a pole, and the coating has remained intact, coming back clean and white.
Furthermore, I would like to provide an update. It has been three years since I applied the RubberSeal coating to my RV roof, and I continue to walk on it regularly. Despite pine cones and branches hitting it, there have been no damages or issues. The roof has gone through Hurricane Sandy in a campground full of pine trees, and it remains undamaged despite being covered in debris.
To conclude, the RubberSeal Liquid Rubber Waterproofing and Protective Coating is a reliable and effective solution for sealing and waterproofing camper roofs. By following the instructions accurately and applying multiple coats, users can achieve great results. I highly recommend this product for its durability and performance.

My wife is no longer complaining about it. Overall, I found this tape to be effective in fixing the issue.
I also used this tape on some seams of my sunroof that were leaking. I applied it along with Rubberseal Liquid rubber, and so far, after three weeks and a few storms, there have been no leaks. I'm hoping it continues to hold up in the long run.
I had significant water damage issues with my 1985 trailer when I purchased it from the previous owner. After extensive research, I came across Liquid Rubber on Amazon and decided to give it a try. The results were amazing – my trailer is now completely waterproof. It is a bit pricey, but considering the investment, it is definitely worth it. I'm optimistic that it will last for many years to come.
During hurricane Florence, we experienced strong gusts of 105mph, and water was driven from our decks under the Hardie board siding where it met the hydrostop deck. I used this seam tape to seal the gap and coated it with foundation hydrostop. The tape worked perfectly for this job, as other caulking products I tried were not up to par. It effectively prevented water from seeping in, even with the strong winds. I'm extremely grateful for this product.
I'm impressed with how easy it was to apply this tape, and it adhered well to both wood and aluminum trim. I would definitely purchase it again and recommend it to anyone in need of a reliable seal tape. While I haven't had the chance to test its waterproof capabilities yet due to the lack of rain or moisture, it seems to be holding up pretty well so far.

The 100% silicone formula and the ability to adhere to different surfaces made it the perfect solution for my problem. I thoroughly cleaned the surfaces and applied three coats over three days. The coating went on like thick paint and self-leveled, filling in crevices and seams. Once dried, it formed a smooth and pliable surface that eliminated the leak.
Although the material is not cheap, it was more affordable than other roof repair materials I had previously purchased. The product exceeded my expectations and provided a long-lasting solution to my leak problem. I am relieved that I no longer have to worry about finding and fixing the leak, and can now focus on repairing the damage to my ceiling.
