Some tips from a novice like me:
1) If you mix colors with thinner or whatever in a color cup on your table, you can use a large soft brush to siphon the liquid onto the brush and "wipe" off the paint into your airbrush cup, that way you don't have to use a mixing jar for very small paint jobs.
2) A substitute to using an airbrush for fixing things, I recommend Tamiya's tiny tiny brushes.
3) Vallejo primer paint, may/will flake off and clog your airbrush, so I always sift the primer paint into my mixing jar. Previous problem of clogging was theb 100% solved after that.
4) Best result when airbrushing, and to avoid orange skin effect, is to airbrush on thin layers of paint, such that the paint dries, as opposed to staying wet and deforming when putting on too much paint onto the surface when airbrushing.
5) Always a good idea to test your spray on a scrap model, especially varnish which may or may not be what you expected (e.g matte/satin).
6) Maybe a good idea to keep a tidy and somewhat clean table, and go easy with arm/hand movements or risk knocking something off the table, or bumping your model or whatever.
7) Basic rule = lower pressure for close up work, may require thinning the paint a little more perhaps
8) Maybe avoid airbrushing at high psi. I get good results it seems with 20-25 psi.
9) Always use an effective air extractor, or risk the paint being blown back at your face/room. And always make sure your filter in the extractor isn't clogged, else the machine won't suck out enough air. Mine clogged up 98% after airbrushing a lot in one sitting, with higher psi, that was scary. If you light an incense stick, you can get an idea how the extractor sucks out air, if it works or not.
10) For airbrushing on a gloss coat, I use Humbrol Clear liquid (acrylic) and I make sure to keep psi at low setting 7-8 psi. I also make sure to NEVER contaminate the bottle of gloss coat, or risk being all annoying never knowing if your liquid is clean or not. Also, any pipette used must be dust free obviously. I keep mine in a bag, and I throw it in the bin if I accidentally drop a clean pipette onto the floor, as I will assume it has become contaminated with dust.
11) I like using acrylic paint, just Vallejo, and it is totall ok, despite what other's say. If airbrushing on a gloss coat, you might want to let all the layers get time to dry, or risk some paint layer at the bottom end up with tiny cracking patterns. Unsure if this is because of primer paint layer, color layer or any of the gloss coat layers cracking up.
