That finish looks just like your Atlas cars, blends right in.
I've found there are three key factors when spraying TC and SC II because I was having the same problem getting a smooth finish.
1. They need thinned more than normal, and with TC I had to use thier thinner to keep it from drying so fast.
2. Higher air pressure than I normally use. 26-30 psi vs the 15-20 I would normally use.
3. Distance of the airbrush to the surface needs to be a lot closer than I normally do, especially with the SC II. Close and slow spray pattern gives the glossy finish, otherwise it's orange peel and dull.
I did a lot of reading online about both of those paints after Floquil left the scene because that's all I ever used. I couldn't figure out why SC II and TC were so different to spray. I still don't know why it is the way it is, but it seems to have worked as far as getting a smooth glossy finish.
