Thanks guys. I really like the color. I like a lot of the Pro-Line colors that they have.
My only problem is... I still had to back it with Tamiya Black rattle can. I was trying to avoid rattle cans completely to avoid off-gassing fumes and the wife's super powered toxic smell detector.
I don't know if it was my prep work, or the way I painted it (multiple layers time in between), but the paint still felt soft after sitting out for a week. Just handling the body some of the paint kind of scraped off with my fingernails.
It would appear the paint had not hardened enough like the Tamiya paints do. So I sprayed Tamiya Black over all of it so that the Tamiya paint would harden up so I could handle the body without worrying about scraping off paint.
I definitely used less rattle can paint overall which is good. So at least I cut down on that. If I have to put one rattle can backing over it, then so be it.
I'll be experimenting more with it and seeing if maybe I have to spray even thinner layers than I did last time and scuff the body up more. It could all just be my inexperience with airbrushing as this was my first time.
I've painted three bodies with Pro-Line paint (same color too - Slate Blue) and all three have had issues with paint adhesion/paint getting scraped off with very minimal effort. I even had a "pro" help me with the paint job on my most recent body. He laid down some really light coats with the proper overlap and we let them dry overnight in between coats.
This third body has been drying now for over a week, and just inspecting the finish, I can't say it appears any different than the first two I shot myself. It's really a soft finish for sure. My airbrush has a .5 nozzle, and I'm running about 30lbs of pressure. Paint flows nicely, so I'm not thinning this paint at all.
I ended up backing my first two bodies with Tamiya PS black also, and it has helped, but still getting some scraped-off paint. I'll probably end up backing this third one as well. I like the darker tone the black backing gives the Slate Blue, even if it doesn't completely prevent paint scraping off.
If anyone has figured out the secret to making Pro-Line paints work better, we're all ears... I'll probably keep using it as-is, though because I too like the better color selection.
