Dicor 351CSB-1 HAPS-Free Cap Sealant - Black, Ideal for RV Window and Door Maintenance

I like that it went on very smooth and being a clear caulk my mistakes are somewhat hidden. Great product and good value for the money.

It's Dicor best brand to use

Box truck for an international 4300 26 footer has been having some nasty leaks on heavy rain days. Found the source of the main leak coming from the side trim leading to the corner install. Lack of sealant in the corner allowed for a free water sliding scenario down the interior wall. Applied this product with basic cauk gun and its tacky. Applied in 90F day so might play a role in the viscosity but the goopy texture was dripping down the sidewall before it would stick. Had to improvise and reapply at angles to get the seal where I wanted. Seems to do the trick although may argue that a simple trim caulk at the local hardware store for $7 might also solve the same issue for less.

Purchased this for our RV roof. It seems to have done the job it was meant to do. It went on the roof pretty easy. We have had lots of 90 degree here and it is still holding up good.

Good for sealing the RV. It forms a skin in a few minutes so work fast. The only issue I have is the shipping can damage the tube and bend the spout. It wasn't broken and it was still useable.

Product has good adhesion and remains pliable

We have used this to fix cracks around our vents in our RV roof for the past few years and it has held up well. We always keep a spare tube in case it’s needed. The gray color matched well. No complaints!

Good quality product at a good price. Much better price compared to the prices at the RV, trailer supply stores near me. The EXACT same product at a MUCH better price. Will definitely buy again.

The silicone sealant was easy to work with

Very satisfied

I liked the way it flowed from the tube with very little pressure. Being new at this was a surprise how easy it was to use I just followed the instructions and was very happy with the outcome I ordered 2 more tubes as I decided to do the rest of the trailer. Also no waste so clean up was minimal.
