I got some thickened epoxy on the sides of my 17LT while attaching the deck. Unfortunately, I didn't notice in time and now it's hard as a rock. Is it safe to assume that I need to sand this down to the clear epoxy before glassing the deck (it's at a place that'll be covered with deck glass when I drape it over the sides). If I scuff the clear epoxy on the sides while doing this, will there be a cloudy spot when I apply more clear epoxy? This is my first build and I don't want to make a irreperable mistake. Thanks for your help!
