It works.

I just needed to touch up a few areas on my RV and used Dicor, which had previously been applied. The previously applied sealant was still in place and held up well. So I decided to use the same thing. It works.

Greater shelf-life

It is often difficult to find this product in the local WalMart stores, especially in geographies where RVers regularly visit for extended periods (for example Florida). But it's always been available from WalMart's online store. RVers know there are only a few self-leveling roofing caulks and Dicor is typically the most popular because it does what it is supposed to do: seals and levels out with no need to 'tool' or spread it because it does that on its own. A key factor with any caulk is shelf life and I have yet to order Dicor from WalMart OnLine that was not 'fresh'. Said another way, they seem to always send Dicor that has been recently manufactured and thus has a long shelf-life.

Does what it says

We had a small leak in the roof of our camper. It was hard to tell exactly where it was coming from so we resealed all the seams and that seems to have done the trick and stopped the leak!! It was easy to use, and did what it said
