Patrick,
Here is a time tested method of mine that has worked for 15 years or more; acrylic based craft paints that were originally made for ceramics and they work on all plastics as shown on my "Hobbies in a Barn" and "Building Historic Dioramas" Facebook pages as well as the kit reviews I have published on Amazon and Hobbylinc websites.
1.) First these paints work for all military, aircraft and railroad colors with reference charts, "Anita", "Creamcoat", and "AppleBarrel"
2.) Airbrush with a 50/50 mix of blue tinted windshield wiper fluid as the paints blend with the alcohol and come out very smoothly and nearly dry which is what you want to have happen, secondly dry them thouroughly with a hand hairdryer set on LOW heat and the paint layers will set up.
3.) Hand brush either straight from the bottle or thin with a little water.
4.) There are no strange odors and the stuf won't kill you, although paint in an oper air place anyway.
5.) These brand paints come in gloss as well as flat and mixing one brand with another won't matter.
6.) For my 1/35th scale military kits I use a thinned black wash of acrylics to coat the entire figure or vehicle and dry the whole thing before drybrushing for detailing.
These are only suggestions for price saving, and odor free hobbies.
I am also published on www.Panzerart.com so check out my work when you can.
All the best,
john
