Side note:
Gorilla tape only sticks to itself, even then it's not for long.
Get some good quality Gaffer's tape.

The coroplast is now coated with dirt/dust-imbedded adhesive residue which is probably why the tape doesn't stick very well. Not sure how I would get the coroplast cleaned up ...

It has to be clean if you want anything to stick ! Try Goo Gone.

I had cut the bottom of my 5th at least 4 times when doing work up under the trailer for slide out motors, plumbing and some electrical. Went to the Lowe's and bought 2x1 6ft wood and cut it to lay on each side of the cut out overlapping the edge by 1 inch. Screwed that wood to the uncut coreplast kleaving the 1 inch over the hole. Put the coreplast up and screwed that to the wood. Was able to get back uop into the bottom by removing the screws when needed. Never had it fail and fall down.

I've cut access holes in several places in the bottom corro. I even cut some proactively so that I could inspect or access things like the emergency slide lead screw. On each of those I cut the panel along 3 sides, and simply folded the 4th side for access. Then zip tied along the 3 sides to close.

Not sure if you think you need to fully weatherproof afterward. I didn't. If you do, the belly tape works well, and combined with the zip ties it would stay in place even if the adhesive let go. Even better might be an overlay patch.

Use aluminum tape, water proof, cheap,& available most hardware and big box stores. Mobile RV repair told me to use it, a year now and 15,000 miles, no sign of coming loose.

At Lowes you can find a spray adhesive,Loktite, that I have used on that black tarp on bottom of mobile homes. It stuck when black tape,
grey tape, and even eterabond wouldn't. Clean good, follow instructions on can, and right after sticking, I used the handle of the sissors to press it. Has held real good.

And the winner is........zip ties!

They closed it up nicely and I didn't have to bother with cleaning off the old adhesive first!

Thanks to everyone for all the suggestions.
