Thanks tons guys! I don't think I can afford to by buying any more sanding blocks..
Just have a quarter and roof to go on this car, then, hopefully, I never tough body filler again. haha..
cboy, I guess it's plexi glass for me! Thanks for the pictures.. My PSA sandpaper is a precious commodity. I wonder if I could glue on some paper clips (As in, the clips on the end of normal sanding boards). Might be so long that the paper would just slide off in the middle though.
