Yupp!! most of the time is spent cleaning, prepping, to get a good bond, need a good base coats, (i.e. Nickel, copper, etc.) then several layers of the top coat, Chrome.. etc. if the amps are too high, you burn it, too low doesn't adhere good, solution has to be just right, easy to contaminate with other solutions, so need to rinse between.. keep brushes separate, then you got to deal with costly Hazardous materials..
