I'm have to remove some wood strips from the inside of my hull to access a stanchion bolt. What glue will hold the wood to the fiberglass but not have such a strong hold that it can't be removed in the future?

Would industrial grade Velcro work?

Strength wise yes, but the strips would no longer be even due to the thickness. Velcro crossed my mind as well
3m 4200.
Maybe. I think it might be a slightly too strong but I could be wrong. I'm tempted to use 3M 90 or 77 but am afraid with the wood constantly trying to straighten itself out, it might not hold. I like the thickness and gap filling properties of something like 4200 when it comes to irregularities in the hull print.

What about "liquid nails" ?

I havent used the stuff in over a decade. What's your opinion of it?

I could also do a dab every six inches of something that's known to be somewhat removable, even silicone. If it doesnt work, I have five more inches to dab something else on. Not that I want to repeat the job but it's an option

When you remove the wood that is in place and attached to the fiberglass then inspect what kind of glue they used and get some of that.

In this application it wouldnt be hard to keep some pressure on it. THere's trim that can be used for temporary, light bracing

How much work do you want to do for this???
If you have access to wood tools, and are not afraid of a bit of extra work, I would recommend planing down the wood a bit to allow the thickness of Velcro.
It would solve your issue of the wood being easily removed and would not make it stick out!
just my .02cents

As little as possible LOL. That is an excellent idea however. I have a router but no planer

I noticed in a pic that there might be screws holding this strip on. Hopefully that's all that's holding this piece on

Try using hot glue to hold it in place while the adhesive cures. A few spots

Have you removed these wood strips yet?

If not you may find that the strips are backed by fiberglass so that they are essentially one piece of wood.

Future you or future owner would hate you for it. Like my PO turned re-bedding a couple of chainplates from a 2 hour affair into an all day affair…:banghead:

I realize it’s not the same application but I hate the stuff with a passion.
I find silicone fairly easy to remove using a Scotchbright wheel or disc on a drill at high speed. For wood, I'd do the last bits with sandpaper so I can control how much wood I'm removing
