Tape for sealing under belly.

[sandy43]

Theirs places under the RV toward the back that is exposed to little birds, mice, bugs, etc.. I've used coroplast tape, duct tape, and AL a/c tape. Even after cleaning the coroplast underneath, nothing seems to stick for very long. Question: I'm looking for the strongest weather proof tape that will stick permanently to anything. Any suggestions.

Scrim tape, if the coroplast is clean should stick for years.

I had to repair the gate valve handles on my coach a couple of years ago. I cut a flap in the coroplast around the area I needed access to. After the repair, I cleaned the coroplast with isopropyl alcohol and applied Gorilla brand duct tape over the flap seams. It's been holding for many many miles, even pulling at highway speeds through storms in Texas. Just looked at it last week. Good as new.

Gorilla tape is remarkable stuff. I use it often to secure Christmas lights on the exterior brick of my home. Stays up for 6 weeks in the dead of winter until I take them down. And even then, I have to really pull at the strips of tape to remove them from the brick.

Have you tried cleaning the coroplast with alcohol prior to applying any tape?
