Re: Hardware Store Epoxy?
As a practical matter, for a 1/8" hole that is in uncored fiberglass?
I might just buy a real short 1/8" stainless steel nut and bolt and bed it in some sealant. No one pays attention to "one more bolt".
Or, I'd break out the white MarineTex. Which isn't cheap but is conveniently durable and available in WHITE so there's no blending or coloring needed, it will look like a better finished repair with less bother.
For that matter, a dab of 5200 or other permanent white adhesive/caulk probably is all you need for a 1/8" hole. This is not a job to obsess over.
