RC car painting is typically done using one of two methods: spray cans or an airbrush. Needless to say your skill level will be the ultimate determining factor since most people just arent that familiar with the intricacies of airbrushing. Both methods have their particular idiosyncratic advantages and disadvantages, however.
RC car painting via spray cans is the choice of many not only because they either dont have access to an airbrush or know how to use one, but also because it can be done quickly. A huge amount of space can be covered relatively quickly with a spray can. But RC car painting isnt the same thing as changing the color of a flag pole.
You want to be proud of that car and make it look as good as it runs. Although personalizing and detailing can usually done much better by airbrush, if you take your time and plan ahead, your spray can RC car painting can wind up looking quite impressive.
Of course, RC car painting with an airbrush is ultimately what you should aim for. The benefits of using an airbrush is that you have access to so many more colors than you can get from using spray cans. And thats saying a lot, because even if you do choose to use spray cans, youll still have over fifty different colors from to pick. But when RC car painting with an airbrush, you can exponentially expand those choices through mixing and blending.
In addition to more flexible use of coloring, airbrushing also affords more control in application. Unlike spray cans, an airbrush can be adjusted, allowing you to spray the paint as thickly or thinly as you like.
The downside to using an airbrush, besides your own level of artistic ability, is cost. For RC car painting with an airbrush youll need a compressor. You can try using canned air to begin with, but youll quickly find yourself spending more money than you planned on saving because they empty pretty quickly. Better to shell out for an actual compressor, preferably one that produces 25 to 70 psi. By pass the 1/8 HP hobby compressors and go for the HP. Since most RC car painting is now done with next generation water-based paints, also make sure the compressor comes with a moisture trap; if it doesnt, youll quickly find car covered in thick gobs of paint.
RC car painting with an airbrush requires not just air, obviously, but brushes. Ideally, you will want to own more than one brush, but since they can be pricythe good ones anywayyou may just want to start off with one. The reason for owing two is pretty obvious. RC car painting at its finest creates a work of art that combines both thick lines and fine lines, therefore you want a brush for both thicknesses.
In addition, the paint itself comes in various thickness and some of the finer brushes just handle the thicker paints at the psi the compressor puts out. RC car painting with an airbrush obviously requires more effort, time and expense than RC car painting with spray cans, but the end result usually shows.
