Mike, as for prep,there is allot! After I get the cabinets built I cover the entire surface with a VERY THIN layer of body filler that has been thinned with Plastik Honey, then I sand them smooth,Heat them up inside and out for about 24 hours to get all the materials to shrink up as much as possible,then I cover the entire suface again with sandable primer,heat it again,sand it spray another coat of sandable primer,heat again,sealer,wetsand down to 800 grit,paint with Nason 2K urethane or PPG depending on how much the speakers are selling for,then wetsand the paint to 1500 after about twelve hours, then I polish with polishing compound with my 7" polisher.
The paint takes almost as long as the speakers do to build. I design and build the crossovers as well. Need some speakers! ?
