Chris, I also have a KR2 and I also restore vintage cars as a hobby so I have a pretty decent amount of experience doing body work and fiberglass. I think you stated this on painting the wheel pants but, prime my initial primer with only true 2 part epoxy. the reason is many. Its waterproof and no other primer is, it will bond to any surface including steel, aluminum and fiberglass composite. Then I spray a filler primer and sand out any pin holes as well as do all finish long board sanding to get a good flat surface. This may require an additional spray coat of filler primer in areas and another sanding. Then, I spray the epoxy sealer primer. Each finish coat of primer is finished with wet sanding to 600 grit. then base color and clear. I have never had a paint failure, fish eye, paint delamination of any kind. I use only epoxy paints in the last 20 years. I prefer PPG Deltron and also Sherman Williams Automotive Ultra 7000 or ATX.

Oh, Very good!!!

My KR is a '77 and still has the retracts. Aquired it in '92. I found it disassembled in the corner of a large hanger covered with 1/8 of dust. Then added wing tanks, built new engine, new electric wiring, new radios and instruments for IFR. It's back in my shop for work and glass panel add. Planning on a spring roll out.

It looks like excellent work. I can work with fiberglass and do it reasonably well but I don't like it so I will probably never build a fiberglass airplane in spite of the speed advantages.

Chris, I’m just wondering…. For filling in pin holes, I wonder if you sprayed a wet coat of primer/filler on the pant and quickly covered it in a plastic bag and vacuumed the bag.

Great video! Can jou let us know what speed improvement you have?
