I am new to body work and I am wondering if any one as an opinion on flexible sanding blocks? I am working on a 41 Ford truck with lots of contours and I don't think I want to use a hard block sander, I found in the Eastwood catalog two flexible sanders (pg.42), an adjustable flexible sander and a flexible board sander. The adjustable one may better due the range of paper 80 grit to 2000 grit (body filler to color sanding) any ideas?
