I've got my seat roughed out using a 4" grinder which worked pretty well. Looks like I'm going to be able to do an overnight "leak test" in a couple weeks (sans varnish or any deck rigging) and want to take something along to do any needed adjustments to the seat. My local hardware store staff, who have done wonders on lots of things for me, have never heard of Dragon Skin.

Can someone please describe this magic stuff or recommend other simple tools for final shaping of minicell foam?
