Use an airbrush with a .4 or .5 tip to begin with. Thin your paint with the right stuff for the paint series...too thin is better than too thick. Use lower air pressures 25-30 lbs. Figure out what "distancing" means. Begin with basic 3-4 color patterns. If you goof up a few times don't let it throw you into endless vortices of despair. Endeavour to persevere.
endeavor to persevere...quote from the outlaw josey wales. i like it! just to piggyback on bois's post. if you don't like the results you get just use a paper towel and some denatured alcohol to wipe off the offensive paint. works like a charm.
