: Question: As soon as the seal coat is no longer tacky, just add the glass and
: then more epoxy? Or do you need to lightly sand the seal coat first (to
: remove small imperfections)?

: Thanks!

Just lay out your glass and wet-out with epoxy. Sanding is not needed. If your cat is stuck to the surface remove, otherwise go on to glassing

The seal coat will be soft, if you tried sanding it it would be like sanding Gummy Bears, you'll push around soft resin and gum-up your sandpaper fast.

All the best,
