Keep your trailer watertight
I bought the Dicor brand, because it was the most recommended on the internet and when my local RV dealer wanted hundreds of dollars to reseal my trailer, this was the brand they were going to use. Instead, I bought it off Amazon for half the price they wanted for a tube at the shop, and did it myself. The sealant goes on very smooth and even. It’s clear, so it dries with a shine, but it’s not too noticeable. It is very gooey, so I brought a few rags and some water to clean and run off, as it can get pretty messy if you’re not careful. I have. 22’ trailer and it took me 2 tubes to seal around the windows, door, and base of the rv. The tube goes a long way, but I was very liberal applying it. Keeping the rv watertight is the most important thing you can do to preserve your trailer, so it’s well worth the cost and I wouldn’t skimp on a lesser brand.

Seals around Rv drains, windows and doors
I needed to repair the rubber stripping at the back of the trailer’s roof. This worked great, but be warned, it is very sticky before it dries and can be messy. Be sure to wear some disposable gloves.
