RE: painting over flex hinges
Bob,
As "bcovish" said, I did nothing at all on my Kingcat and it worked just great. I used a PPG basecoat/clearcoat system and had no problems whatsoever with cracking, etc.
P.S. I was up at NASA Langley this past week on X-43 simulation business and visited the Tom Strohm to transfer a 10X program with his DataSafe cord. It looks like the GTM project is progressing fine.....
