I would like to attach my fuselage panels with countersunk screws and dimple the panels. As the screw tightens home, it will tear at the paint. How would one avoid this? I can visualize a very thin countersunk stainless steel or clear nylon washer, but I cannot find anything on the web. The tinnerman countersunk washer is close, but without the big flange.
