Thanks!
I used Testors Intermediate Blue from a rattle can for my 1/72 ones and it seemed a perfect match, but I hate Testors enamels, they sometimes take days or even weeks to fully dry, plus being a rattle can, it's hard to get subtle variations like with an airbrush
Vallejo paint will make an excellent alternative for when I do mine!
Also regarding the photo-etch, did it plug in pretty easily, or did you have to do some sanding/cutting. I was wondering since I have the same set
