Not a super cub question but, I Looked a a couple airplanes recently that had been stripped and being prepared for new paint. What are the rules regarding sanding universal head rivets? How far down before it is not airworthy? Maybe 10% of the rivets still had dimples many where down half flat and some even lower. Not really wanting opinions here but real standards, if there are any. What I remember from A&P school is you don't sand it at all, if the dimple is gone you replace the rivet.
