    • Good product. I will buy it again when I need it.
Size: 1 Gallon
Sealed my RV roof. Had plenty to spare. I went around the outside of it so not a full paint job. But all the vents and AC and such. Works good. Good thick quality. A good product. Covers well. No leaks now. Easy to use, just like any standard painting.

    • Its thick. I need a 2nd can for 2nd coat
Size: 1 Gallon
Cleaned then masked off the sides of a 6x12 utility trailer. Went around the edge and gooped it on with a paint brush. Used the rest to coat the top of the trailer. Had just enough for one coat and need to get another gallon for a 2nd coat. Shipping is great. Comes in a well protected box and the lid is fully secured. Guessing have had spills in the past and been corrected. Good product, and good shipping method ... show more

    • Good product & value, but temperamental to put on.
Size: 1 Gallon
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.) ... show more

    • Great for pop-ups and gel coated campers!
Size: 1 Gallon
Used this on an older pop-up camper that has had a life. Most of the paint on the roof was down to the aluminum, and someone had done a home seal job with about 15 tubes of calk. Needing to do something a bit more legitimate, and give the camper some longevity, I decided to purchase this along with the removal of all prior sealing attempts. After cleaning off the old gook, and resealing seams we applied this over the course of a weekend in several coats. Here is what we found. A year later, its held up wonderfully- better than the paint that covered it, for sure. The coating goes on very thin. It will take several iterations before it becomes solid white and thick We used more than we thought. The lid to our small pop-up took about half a gallon to provide a reasonable coating. Dry times for us were much shorter than the 24h it recommends. This may have been due to low Colorado humidity, and that we did it in a controlled environment inside The coating takes pants and other things very well. After a full day of dry time, we were able to coat this with paint (Rustolium water based) and it adhered well and looks good. Time will tell on durability, but for now we are happy with the results. I would recommend this if you are looking for a paint like substance to seal imperfections on a roof. ... show more
