I have a couple holes to fix and need to with body in right orientation. I have used clay to back the spots so the epoxy stays put but it’s hard to get it sealed so it doesn’t run through. If I needed to thicken up epoxy so it wouldn’t run so easily, what’s the best way to do that? I used to have flocking that was super fine but I can’t find that stuff any longer. Can I grind up some set up fiberglass and use the dust? Will it affect strength at all? Some spots will have new holes drilled through so i need it to still be sturdy enough.

Thanks for your input.
