Once the glue/resin has dried 24 hours it's time to start making it pretty. Some of the roughest stuff can be strip off with a nice sharp utility knife/razor. Then just sand all the ugly stuff off until you get to the nice wood underneath. I usually start off with some real rough paper like 50 or 60 grit and work my way up to about 180 grit. Some sort of power sander is almost a must here. It takes quite a bit of sanding to get all the bad stuff off and it's very messy. I would reccommend some sort of mask over your mouth and nose. Once sanded, notice I am now aloud to bring it in my house, picture above right.
