Yes Larry, Steve believed, from many years of experience with the process, that doping through fabric would glue it to the structure, allowing him to skip a step. He got away with it except for on his ailerons, which delaminated, fluttered, and departed the aircraft. I don't think the KR has any aerodynamically-loaded fabric. Scuffing gives a good mechanical bond, peel-ply a better mechanical bond, and saturating the cloth and wood in one application a superior chemical bond w/epoxy...but not with dope! Peter
