This RV caulk doesn’t have any discoloration over time. I notice that a lot of sealants have this weird shade of yellow over time. This one seems to be able to blend with the color of the material it’s on. That said, it’ll be easier to sell your RV in the future because this sealant can help make it look brand new at the very least.I don't really have to worry about where to buy decor sealant after using this caulk from Dicor. It can prevent leaks and can stay sturdy even when the rain pours down on it. It also has very strong adhesion which makes it very sticky and able to hold still on pretty much any material. It can hold its own on aluminum, fiberglass, wood, vinyl, and even concrete. Aside from adhesion, it’s also really flexible and able to seal cracks and holes.
