after seeing what all of you know ill give you all some basic techinues with the caps. for me i just drain most of the areosol out of the can by turning the can upside down and alowing some pressure to get out. i'd only do this for about 30 to 40 seconds depending on how much paint is inside of the can. the results are good since you only would have to use a fixie( aka) ny thin and the lines are pretty thin. and that rusto thin is pretty good but i think if you can master pieces with ny thins you can do just about anything.
