AMES RESEARCH LABORATORIES MSS1 Maximum Stretch Roof Coating, 1 Gallon, White

I've used this product twice now. I'm pretty impressed. I have a 30 foot R. V. That i'm trying to keep cool enough for my dog to survive. If you put your hand on a roof from the old blackened rubber, it'll burn your skin. When I put my hand on the roof that was painted with the white stuff, it was literally cool to the touch. It says eighty eight percent refractivity, but I suspect it might even be higher. It's insanely bright, and I had to wear very dark sunglasses to even apply it. But that's good that's what you want. I think I mixed it well enough. But it does seem like you need to apply a good four or five coats, like some other review, suggested.I did the roof and now i'm gonna scrub all the sides of the r v. and literally paint the entire rv with it. That should reduce my strain on my solar panels to run my air conditioner. This time I'm going to use a sprayer as an experiment, partially because of the sheer square footage that this project will entail. I've looked at other products at ace hardware for instance, and I think you get a lot more for your money here.

Seems good. Only time will tell for longterm.

This stuff is great. Goes on like thick paint and levels out to a smooth surface. I used a short nap roller and long handle. Highly recommend.

goes on pretty thin, need to do at least three coats. looks good, hope it lasts

Value and quality. Covers well. Easy application and cleanup.

Haven't had any rain yet but application was easy, used a brush and roller,looks great and I trust it is sealed 100%

I purchased a used motorhome and the roof has never been sealed. After researching several different brands I chose this sealant from Ames after reading multiple reviews. It goes on easy and I finished putting on the second coat today. It looks great and I can already tell a difference with lower inside temperature in the hot, Florida sun. This should make camping much better this summer.

This product is good. If you are bushing and rolling plan on at least 4-5 coats. The product shrinks 50% so apply thick coats
