I have a complete set of Dura Blocks but my boss wont let me use the long boards, he says there not straight. We do have the 3M ones and I like those. Most of the cars we do hae long quarters and doors.
When we color sand we start with 500 grit dry and wooden paintsticks but I will hae to give the plexi glass a try.
The avater pic is a car I have to do in spring. Since its glass it has alot of imperfections. I am definitly going to take the pad off of those Hutchings boards and see what happens.
