I was reading my new supply line and David Doyle keeps coming up with the pertinent articles. I will need to spray my M151A1 in the near future. After reading the article I was thinking about down epoxy primer first (I am stripping the body down to bare metal). I then going to do the filler where my patch panels are. Just enough to do the job and no more. I then planned on putting red oxide over the top to keep the original look. My only other plan was going with the red oxide only but the advantages of the epoxy primer would help me out with the body work and filling in the sanding scratches and such. Can one of the experts tell me if red oxide (gillespie synthetic enamel) is ok over the body filler and the epoxy primer. The primer will be Urethane most likely.
