belly liner repair

[unclescratch]

Don't know what you call it, but the corrugated plastic that closes-in the belly of my 5er needs help. After a few repairs to dump valves, I need a good product to seal-up the bottom. 'Duck' brand duck-tape just doesn't hold-on very long and I would like to find some type of (wide, maybe 4-inch) adhesive tape to close-up the bottom. Any sources for something that really works?? Thanks, folks.

I stitch it with zip ties every 3 or 4 inches, then cover with Gorilla Tape. That way you can get back in there, because you probably will have to.

Maybe try tarp repair tape. TSC usually has it. I would think if it can withstand the wind on the highways on the back of a semi trailer it might work for you.

Another vote for Eternabond.

If all else fails there is Eternabond. Sticks very hard and won't come off.
There are other construction peel and stick membranes as well that will work.
Duct tape is useless for that application. It dries out and crumbles quickly.

I used Eternabond on ours.

That 4 inch wide gorilla super strong tape works well.
