Dicor 551LSW-1 HAPS-Free NON-Leveling Lap Sealant - 10.3 Oz, White, Secure, Ideal for RV Roofing, Maintenance, Repair, Appliance Application

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.

Easy to use and does what it’s supposed to do

This is probably the universal standard for RV’s.I have used it a lot both sag & non sag.Works well when applied correctly.

It's a great product that is recommended by most RV manufacturers for sealing or resealing most roofs. (Check your owners manual) Tip..I like to use it in conjunction with self leveling to contain it

Have used this product for several years now on our Motorhomes and enclosed car trailer. Would Recommend!
