: I have the two halfs of my guillemot together and the whole outside sanded.
: My question is when I apply the fill coat in two stages how do I keep the
: resin from dripping down the sides while it dries? Is this a dumb
: question? Am I going to have drip lines on the sides no matter what?

I put MAS epoxy with slow hardener on with a short nap foam roller. It was easy to make thin coats without a single drip line or sag.
