One note, they have FAA certification and provide some pretty high-end
coating products to the race industry.  Would be nice to know what temps
there coatings are good for....

You do have to admit tho, those "tattoo" coatings are just way cool... And
if ya want "chrome" without having to be "chromed", they can do it...

I've not used them, just happened upon the site....
