Review: 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.
