For those of you who are willing to disassemble your precious OM-[34]T(i) to renew it's youthful good looks, or if you happen to have an SR-71 lying around that needs a paint job, this notice just arrived in the August 1999 "NASA Tech Briefs":

"Method for Surface Texturing Titanium Products
(U. S. Patent No. 5,853,561)
Inventor: Bruce A. Banks, John H. Glenn Research Center

This patent discloses a method by which the surface of titanium and/or titanium alloy objects... may be electrolytically textured with a pattern of uniformly configured "pock mark" pores or pits... The process employs an electrolytic cell in which the object or objects to be textured are immersed in a sodium chloride and water solution... [and] electrically connected to the positive terminal of a DC power source... During the electrochemical process the electrolyte is agitated by an ultrasonic transducer."

So, get out the battery charger and kitchen salt, and be sure to shake it up good. Then you'll have a surface that will hold paint better!
