This is an amazing product. Stopped all the leaks.

### ⭐⭐⭐⭐ Good product & value, but temperamental to put on.
*by "***" on November 10, 2022*

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.)
