based on my 2 frame painting experience

rattle can can look fantastic, but it is not anywhere as durable as automotive finishes

To do the job right it takes a lot more time and costs more than you would think, even for rattle can

have to have a respirator
Strip frame to bare metal (chemical stripper)
clean oil from frame
Acid etch primer
Sandable primer
sand
color coat (multiple thin coats, best to plan so that you can re-spray as soon as the respray time will let you)
clear coat (mutiple thing coats, gain watch respray

My first job, rattle can one, is looking really ratty...... when it is so ratty that i overcomes my laziness, I will strip the components and get i powder coated
