Ivan Ivanovich Posted September 10, 2018 Share Posted September 10, 2018 (edited) The radomes had a so-called "rain erosion protective coating" applied that was less prone to the weathering effects than the predominantly used fuselage epoxy/PU topcoats. The radomes just didn't age that quickly, hence their rather fresh and consistent appearance. Edited September 10, 2018 by Ivan Ivanovich Link to comment Share on other sites More sharing options...
Ivan Ivanovich Posted September 10, 2018 Share Posted September 10, 2018 (edited) Even freshly applied RAL 9006 has a very dull metallic sheen. Like Jennings said, nothing remotely shiny. Many conventional aluminised topcoats consist of clear base lacquer with a more or less specified amount of aluminium powder to be added. RAL 9006 isn't much different, save that it uses a light grey base substrate. The older a RAL 9006 topcoat gets, the duller it will appear due to oxidising Al particles. On operational aircraft, however, you could still spot that dull, subtle metallic sheen - even if "well aged". The belly of the beast...

Chek Posted September 10, 2018 Share Posted September 10, 2018 Olive green was a widely used anti-glare colour on many century series jets, up to the F-110 Spectre. Bill Cross 1 Link to comment Share on other sites More sharing options...

Bill Cross Posted September 11, 2018 Author Share Posted September 11, 2018 Sounds like Alclad flat aluminum would be a good choice. Link to comment Share on other sites More sharing options...
