Help with Resin

I concur about the dangers of resin dust, which is why I prefer wet sanding to remove the last traces of pour stubs. If the resin is not very brittle, sometimes you can score the stub with a knife and break off some of the excess. I have ground off excess with a Dremel tool, but that's dusty! I usually remove resin from the pour stubs with a razor saw, and for small parts the photo-etched saw blades for craft knives might be useful.

Make sure to degrease all parts with soap and water, if not you'll have surprises when it comes to painting time! Resin dust, that you'd get from any sanding, is very dangerous to your lungs. Wear a mask if at all possible.
