Is a pain in the butt! I'm either doing it wrong or have the wrong equipment. It took me 3 hours to sand the clearcoat, paint, primer and MOST of the factory paint from *ONE* of my elky fenders. I don't think it should take that long.
Used 60/80 grit with theses 2 tools : http://www.amazon.com/Ingersoll-Rand-4151-6-Inch-Vacuum-Pnuematic/dp/B00004XOT6/ref=sr_1_1?ie=UTF8&s=industrial&qid=1291834205&sr=8-1 and http://www.amazon.com/Porter-Cable-7336-6-Inch-Variable-Random/dp/B0000222YH I alternated so as to not overwork either and allow the compressor to cool. BTW compressor is a 60 gallon 5HP Kobalt. Still need to finish it up, but the remaining paint/primer was coming off comparatively easy. I am using Norton & Mirka paper. I also bought a sanding backer for my grinder but it was difficult to keep from gouging the metal. Do I need a 7inch or larger sander? Recommendation on brand? Coarser paper needed? I want to do the entire car and finish it in this lifetime, Thanx. -- Rick Schaefer 72 TPI El Camino
