colorman, now that you have volunteered...
Have had two exec aircraft painted in the past with Imron, and indeed my present aeroplane is painted thus, and the paint still looks good after fifteen years.
Imron gave lots of problems in the early days due to poor surface preparation, but once these areas were ironed out, I personally have found no other paint to be as tough and weather resistant.
Am considering purchasing a twin turbo-prop exec aircraft in the near to mid-term and wonder what other paints are available.
The only aircraft painting that I have had done recently is on a TriStar fuselage...Boeing grey, not my choice.
