Amp board adhesive / glue

I have had some issues with amp board mounts losing adhesion and coming off.

Used an epoxy for the fiberglass (hull) to polymer (amp board stand offs). Then tried Loctite PL and had mixed results.

Hesitant to use 3M 5200, thinking maybe 4200 quick cure.

Now using wood standoffs, not happy with the poly that I was using, and not too enthused about going on an easter egg hunt for the perfect material for these, 2x2 wood blocks will more than serve the purpose IMHO. My local HD did not have any Trex scap to try.

Since its mid season, I want to be boating not messing with things until the off season.

Thoughts?

Not quite sure w/o looking - but there's a couple ways dealing with epoxy in difficult small areas.
Source - Hobby store has shredded glass in small amounts to mix in with the resin prior to catalyst.
Some plastics don't take well - so a special prep is needed to hook up good.
Like Dremel cutting wheel to under score the surface.

Then bridging the compound onto small components.

The 5200 if bridged heavy - would need to cure overnite - but it would create a flexible mounting to absorb shock quite well I'm sure.

I'm definitely a fan of the two-part epoxy from Loc-Tite in the two squeeze bottle kit.
