Dicor VS This product
I needed to reseal everything on my RV roof. i had four tubes of dicor left from a past project. i needed 10 tubes to complete the project. I couldn’t get more Dicor in time so I ordered this product. Using them back to back, its very similar to dicor. This product maybe 10% runnier, thats all I noticed. Runny is fine in my opinion as you want it to flow out. overall, good product So far, time will tell. See photos, the antenna is sealed the Dicor and the 2 vents are sealed with this product.

Good product
Worked great but was a little more runny than other brands. Don't use close to the sides of your rv

Great product with best warranty….
This stuff goes on easy,self leveling and dries fast.It appears to stay flexible too.I’m so happy with the way it covered the seams I’m going to order the big bucket and put it on the whole roof.

Good product, but only three out of the four worked.
I like the product, but only three out of the four tubes worked, one of them busted out the back!!! And no, they were not sitting around. They were purchased two weeks earlier then used. I also made sure to puncture the hole….
