Buy lots! Works great and you’re going to want 2 tubes
Great product and smooths out nice and flat. When they say self levelling they mean it. Don’t try to use on anything vertical. Used with dicor roof repair tape and then redid as many things on the roof that I could with what I had left, wish I had bought a other tube. I’ve heard mixed thoughts on removing old sealant before applying new vs just cover the old stuff. Well my old stuff was in good shape except the expected weather checking and cracks so I just went over the old stuff to maintain water integrity. It went over the old just fine and adhered well so far as I can tell. It smoothed the sealant our like new and removed the water traps. If I had a leak I would probably remove the old sealant and start from new but for touch ups, like I said, buy lots!

5 Stars
This is one of those “buy it every year without even thinking about it” products—and for good reason. My boyfriend swears by this non-leveling sealant for the camper, and at this point I trust it purely based on his loyalty alone. If something keeps making it back into the cart year after year, you know it’s doing its job. We haven’t used this specific tube yet, but past experience says it holds up, does what it’s supposed to do, and saves us from bigger headaches down the road. Five stars for consistency, reliability, and for keeping the camper in one (non-leaky) pieve.
