Advice please

OP here.

I went with the Gorilla two part epoxy. I mixed it in a large syringe from Walmart and applied under the trim. I cleaned under the trim with rubbing alcohol before applying.

I positioned a board with a little force on top of the trim. Looks like this will work just fine.

Will remove board tomorrow.

Note: If you want to use this method, be ready to apply the epoxy ASAP, as it sets up in the syringe in about five minutes.

Thanks for the input.

Gorilla or GOOP Goop is not as strong but it is easier to use.

I know that I have had great luck using the Gorilla products. Perhaps you may find one of their adhesives that will work the best. The most important thing is that you use something to get inside the gap and clean the surfaces with alcohol first to insure a good bond. Determine what the composition is of the two surfaces and then do a search for the best adhesive.
