Great Caulk
This caulk is great for installing anything on your camper roof or sides. It flows smoothly and looks like factory caulking. I would recommend it for all your sealing needs.

Better than factory seal
This stuff really did a great job sealing up cracks in the original sealant on my camper. It looks better than the stuff that was on there. I am very confident now that water is not getting into the camper. It is very sticky. Be sure to have plenty of clean rags and mineral spirit on hand to keep it nice and neat.

Good, Flexible Watertight Seal
This product creates a good, flexible seal around an RV's exterior openings, especially when installing new or replacement parts/ equipment. The "no-sag" sealant works well on horizonal and vertical surfaces. It is still more viscous than many household sealants, and can be a bit messy to use and clean up. As a result, our nickname for the product is "guckempuckie". With care, it can give you a good, watertight seal that looks good on your RV.
