epoxy can be some nasty stuff. especially if you are fair skinned. like blondes and redheads. I have seen some nasty allergic reations over the years. dont keep getting it on your skin and if you do, don't wash it off with acetone!

it will dillute it and drive it into your skin. wash with soap and water. gojo works really well. when its cured however its pretty benign. you still want wear a dust mask when sanding. of course you should do that with anything.
happy building
