This is the 3rd gallon, I have purchased, excellent multiuse product. Does not seem to become yellow with time! Excellent service and quick delivery. Alexd

This roof coating goes on smoothly and provides a strong, flexible seal. The white finish looks clean and helps reflect heat, keeping things cooler. It’s thick, durable, and really does stretch as advertised, making it great for sealing cracks and protecting the roof. A solid product that gives peace of mind knowing the roof is well protected. Highly recommend!

Excellent product, AMAZON DELIVERY SUCKS THOUGH

Bought this for my aging RV camper. It was rated well, went on easy and did the job. Great price.

I used this on my camper roof. It's a smooth metal roof in good condition so I didn't want to cover the good roof surface if not needed. However, all the vents & railings, etc., were getting a little... tired? looking, around the screws & stanchions. So I cleaned and prepped the entire roof and all the items. Then taped off to only paint around the perimeter where the railings and vents and A/C are. (Basically, everywhere anywhere near screws.) Cutting in everything was done with a brush. The paint is much thinner and slipperier than I expected. Thought it would be more sticky & heavy. So it didn't cover easily. (had to use a soft brush to not pull to much off when applying. Rolled the rest and it had a tendency to not lay down very thickly. Also, a big problem, was that it bubbles a lot when rolled on. If you let it sit a few seconds (to tack up) as you move on, then go back and lightly roll over it to pop the bubbles and even it out, it gives a really nice even finish. Sadly, I had to do that 3 times to get enough thickness. In the end, it came out very nice. This stuff reeeeally sticks well (on almost anything including your hands). I saw quite a few people say it didn't cover as much as stated. But I found it covered quite a bit of surface and all 3 coats equaled about the amount they stated for coverage. (In my case, about 50 sq. ft. & 1/2 can.)
