The product is easy to work with and it keeps out the water!
I looked at a number of different products to use on the roof of my RV. It is an older RV, 1985 and other owners had removed air conditioner and roof vent. The patches were poorly done, and were done with various materials. I decided to go with Flexseal having used the product for other purposes and being satisfied. When I was on the roof I noticed a weak spot with the material being broken in several places. I decided to use a piece of roofing metal and cut it to size. I then used construction adhesive to glue it to the roof. I placed weights around the edges to get a tight patch. I then applied the Flexseal over the patch. Totally on the patch I put three coats and put extra on the edges of the patch. I purchased the 2 1/2 gallon size and I was able to cover the roof two times with material left over. It is a class C motorhome measuring 25 feet. For the first coat I used a roller for the center and a 3 inch short bristle brush for the edges and around fittings. The roller leaves a little thinner application so I used the brush only on the second coat. Each dip of the brush only covered a 6 inch by 6 inch area but I was able to apply it thicker. There have been several hard rains since it was applied and there are no leaks. I am pleased with the product and would recommend it.

BEST IN THE WEST
Bought this product 9 years ago for a flashing leak on my fireplace and it is still holding up, I have put this product on my RV roof now for a soon to fail vinyl top and same, I feel, will keep the roof waterproof for years to come. Save yourself the money, the RV shop quoted me $7K to replace the membrane!!

Very bright, very water proof. Used along side of grain bins and lowered spoilage along edge by a significant amount. As long as you are ok with white then great, paint will not adhere to it.
