Zank_Frappa Posted June 22, 2017 Share Posted June 22, 2017 So, I'm looking to do an "unpainted" f22 here, and I came across a ton of images and footage of unpainted f22's lookin' all funky and green, seen here: What I'm wondering here is why are they that color? Is it, like, a primer that's put on to protect the airframe? Something to aid with stealth? I've heard they put a special coating over the planes for that, I think. I dunno. I have zero knowledge about modern aircraft, so excuse me if this is some super basic thing. Link to comment Share on other sites More sharing options...
CANicoll Posted June 22, 2017 Share Posted June 22, 2017 I think you hit the nail on the head - probably some sort of undercoating before the stealth coating gets applied. I'm fairly certain SOMEONE here has more direct knowledge of what that green stuff is. Chris Link to comment Share on other sites More sharing options...
Tnarg Posted June 22, 2017 Share Posted June 22, 2017 It's all that panel line pre-shading trick they learned from the modelers. Tnarg Jolly Roger and Zank_Frappa 2 Link to comment Share on other sites More sharing options...

Zank_Frappa Posted June 22, 2017 Author Share Posted June 22, 2017 Reed hope those were helpful. Haha yes, they were. I actually got the idea to do one like this from the video on 4195. Link to comment Share on other sites More sharing options...
Martinnfb Posted June 22, 2017 Share Posted June 22, 2017 That would be the result of the development between Nasa and Lockheed for advanced LARC-TPI polyimide primer. Beautiful stuff if you interested in chemistry. Link to comment Share on other sites More sharing options...
Martinnfb Posted June 22, 2017 Share Posted June 22, 2017 (edited) so they cheap-out on the primer LOL Edited June 22, 2017 by Martinnfb Link to comment Share on other sites More sharing options...

Beautiful stuff if you interested in chemistry. I actually think I came across something regarding this on a forum. It's a newer, less invasive primer without chromium added, right? Oops, didn't see someone else covered this lol Edited June 22, 2017 by Zank_Frappa Link to comment Share on other sites More sharing options...
Out2gtcha Posted June 22, 2017 Share Posted June 22, 2017 That green primer is certainly interesting! Seeing as they mentioned the next few decades with the Raptor, its interesting to think about it in services to other countries (never happen, but some of the schemes are super cool!)
