If you want your RV to be sealed properly, this is the stuff you have to use.

Used this product in every install of vents in my trailers over the years. Levels itself and seals perfectly. Recently installed a Fantastic Fan in our truck camper and once again it was easy to use and set perfectly.

Last minute fix before a road trip, didn't have time to wait for the Marine Tex Flex Set Flexible Epoxy Adhesive (not sure if that will work either) so I gave this a try, and it worked. I've read that nothing sticks to polyethylene, I tried JB marine weld and it peeled off like a rock hard band aid.I had half a tube of Dicor laying around and I was pretty desperate, I put some on my finger and pushed it into a dripping crack, the drip stopped, I dried the area around it and applied more, let it set overnight and then put on a second coat. Worked great, hasn't fallen off yet. The crack is in a bad spot right on the bottom of a 45 gallon tank. The way this stuff sticks to your fingers, it must be good. Works great on the RV roof, I'd rather use this stuff on my home than anything else.Not sure how long it will last on polyethylene, if I have to reapply it once a year, I'll be happy. When I store it in the cold for the winter, that will be the real test.Thanks, Dicor! Great stuff. Saved my road trip, one month now, still not leaking.

Bought this to seal up our Outfitter truck bed camper. The results were really good and it was rain ready pretty much immediately, which was great, because it started raining as soon as I finished the job. Prep the areas where you are caulking prior to doing so and cut a small 45 degree opening for the tip. You don't want to over apply. I used mineral spirits for prep and clean up. Make sure you have plenty of mineral spirits handy.

There isn't a better sealant for campers. I love all of the Dicor products.

good product excellent seller

Works as it should

Dicor makes excellent sealants, and this is no exception. I used it to seal between the end caps and roof on my motor home. Worked just as intended.

I have used this brand Dicor for years on my travel trailers and truck campers and have had no problems I also use Dicor self leveling caulking and have had no problems.

Great product. Easy to apply. Have used this before on my RV. A

Used this to install solar panels on my RV. Worked great and 6 months later, not a single leak!

Great product. Recaulked roof on RV. Self leveling, just as the directions said. Easy application.

Good product

Pretty good stuff...

Worked great on the roof of my RV.A friend told me about this , although I didn't realize there is self leveling and non self leveling . But either works great . It holds up through all weather conditions.

Works as it should well worth it and highly recommend!

This is very strong, I used it around my camper van and worked well,

Dicor products lead the RV industry in sealants. I have been a long time TV owner and will not use anything else.

Works as intended, covers great and easy to use. Happy customer!

Very good stuff I will be ordering some more soon
