KR> Sealers and UV protection
Hello fellow enthusiasts This "info" session seems to have invokef some passionate responses. Many things can be used to seal wood adequately from airborn moisture. There is a UV additive available in body shop supply (not auto part ) stores. It is not cheap but very little is required and the protection can not be beat. So many opinions and ways of doing the job are out there that we need to express what we know without discounting others knowledge unless we know something is a dangerous practice. I have been involved with homebuilt aircraft including working with a NASA engineer on a glider for iver 30 years but still need ti be open to learning. Live well...fly safe...build conservatively.

KR> Sealers and UV protection
Almost hate to chime in as my question isn't KR related, but there has to be others like me that find the KR site the most informative out there. So... When sealing wood that fabric will later be glued down to, is there anything I should look out for? I assume I should scuff the varnished/poly/epoxy surface where the glue will be applied to help with adhesion. Thanks Kevin Golden Harrisonville, MO Streak Shadow.

Hey Kevin, I'll send you a message off-list re: your application.

I think Steve Wittman was killed when the wrong process was used to cover is O/O special when the fabric de- laminated from the wood on the wings. Make sure you use the correct process as advised by the materials manufacturer. Larry Flesner

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!
