The cowling was way too thin and damaged with chipped paint missing so I decided to add thickness. Because epoxy doesn't seem to do well over polyester and my old K&B resin looked like Jello, I decided to buy a quart at the local auto parts store. I wet sanded the paint off the cowl, cut patterns from stiff paper, cut lft, rt, top, and bottom pieces of 6 oz glass and applied them to the inside of the cowling to triple the thickness...
