you must not get out alot!. also, i do not buy sandpaper for just one job, or by the little pack at the store. i buy 10 rolls of 100 sheet per roll,3 gallons of primer, etching,........ alot cheaper when bought by bulk.
Well, that must be part of it. Since you go through so much, I'm sure you can get it cheaper. Also, depends on what brand and type of materials you're talking about. Maybe if I hunted around and went with single-stage I could do it for that. Also might depend on the area/region. Because I know that here, in 2-stage, I can't see doing it for $700. You're the man. I'd really like to see one of your restos in person sometime!
