yep I can give you some advise even you can find guys with more experience here!!!!!
I use two type of AB.... the badger 100 lg (20%) and the IWATA HP-BH (80%) and take usally my air between 15 - 10 PSI.
take your color very very tinned the people says like the milk but I say like dirty water.
use a lot of transparent color and rembember you spent a lot of money for model kit, Ab and so on....don't try to save for the color....only the best!!!
ciao
mauro
ps and yep sorry for the pred from clear color to dark color for the skin!!!!!
