Captainkirk's Duster project
Are you wanting a cheap gun to shoot the engine compartment or a good gun that will do the whole car?
Big difference, just to shoot he engine bay and do door jams etc the cheap purple harbor freight $15 one will work fine.
For a nice overall gun I have a LPH400 Awata, not cheap, but the paint jumps on a vehicle with no effort, worth the money, but they are around $500, but the paint lays down so nice.
