: Last weekend I glued hull and deck together (Bear Mountain Endeavour). This
: weekend, I cut some ash rub-rails, and glued them on at the sheer, to hide
: some screw holes.

: I wanted to glue on the rub-rail without using any fasteners (Moores method
: calls for more screws), so I hot-glued a series of guide blocks to the
: hull, to line it up properly, and hold it in position while the glue
: cured. That part worked fine, but after I removed the guideblocks, there
: was a milky-white discoloured patch underneath some of them.

: This is not glue residue. Sanding has no effect on it, as if it is deep
: inside the glass/epoxy layer. In other spots, the hot-glue residue sanded
: off fine. This only happened under about half of the guideblocks. (If it
: was in a regular repeating pattern, I could at least pretend it was
: deliberate, but no such luck).

: There is no glass weave visible. It is just a milky-white discoloration. The
: only thing I can think of is that this is heat damage. But I have never
: heard of this kind of a problem with using hot-glue? Anyone seen this
: before? Aside from peeling off a patch of glass in those spots, can anyone
: suggest a fix?

Hi Ken -

Maybe try to get the epoxy to go clear again with a heat gun?
