Best With decent value: Rvhouse putty Sealant Tape

Buy on Amazon

The rvhouse putty sealant tape might be a relatively new release, but it's still nothing short of impressive this year, thanks to multiple price cuts and added new features over the past few months. There is so much less mess using butyl tape than using caulking compounds. It’s almost like a tape that is made out of tar. It adheres very well. It works well to seal rv roof caulking and side seams. It gets a little sticky when warm, but you can always throw it in the fridge and make it more firm again.

This stuff is really sticky, but using one hand to lightly pull on the cut piece while cutting works well. It is great for re-sealing rv windows. It would make your installation much easier if you can put the putty tape in the refrigerator for about 1 hour when the room material is higher than 62 f. It works well to seal rv roof caulking and side seams.
