That's the primer showing.
Point taken. Especially since I always have a spare body sitting by the paint booth so I can test out the airbrush. All I had to do was grab a fresh one and give the whole thing a full paint job and check the results. Probably me showing my cheapskate side (comes from my Dad).
My local hobby shop recently got in a new paint line call Cobra Motor Paints by Ammo, which includes some factory stock and racing colors. I picked up a jar of 60s Ferrari Rosso Corso and light brown leather. I already have a spare body ready for a full test before it goes on project car.
I didn't mention it in my initial post, but while I have been using MCW paints for a long time, I've been way less than satisfied with the results. Specifically it's the level of gloss. I got back into modeling during COVID after maybe eight years. One of the first kits I painted was the 58 Imperial that's out now. I used MCW 58 Imperial Dark Turquoise with a stainless roof panel, and it looks fantastic, nice and glossy. Other bodies have been less so. I can get it to lay out perfectly smooth, but often it looks more like semi-gloss. The 55 Chrysler 300 came out that way, smooth but not very glossy.
I had the same problem 15 years ago. The gloss level seems to depend on the day of the week, the phase of the moon, and what I had for breakfast. Weather doesn't seem to make a difference. I just re-sprayed a chassis component for long-term NASCAR Daytona project out of the same jar I used earlier, and it came out a little shinier. I've gotten so frustrated with it I wanted to try something else.
I get very consistent and very glossy results with Tamiya. I just airbrushed a Tamiya Alfa Romeo Giulia Sprint GTA body and chassis in Italian Red and it came out PERFECT. But Tamiya only has so many colors to pick from.
One thing worth noting. I used to have an HO model railroad, and I hope to have one again someday. About a year ago I decided to paint/repaint some locomotives to display on my bookshelf. MCW has a line of railroad colors now, and I ordered some CSX yellow, since I couldn't track down any from Badger Accuflex. HOLY COW, that's the glossiest result I've ever gotten from MCW, and it flowed out beautifully. The water-based blue and grey fr om Badger went over it with no trouble. I see on their website they are offering a lot of their car colors in the new enamel formula. I'm thinking next I'm looking for paint, I'll give MCW's enamel a try. And yes, I'll do a full spray-out on a test body first.
