Paul, when it comes to cleaning those door jambs, hinges, or any other painted area on the car that you want to repaint, this is what I did and it worked great. I used PPG Acryli-clean # DX330 ($32.00/Gal.)for the "chemical" and then I used 3M Scotch-Brite pads # 7447 for the "scrubber" At the same time that you are scrubbing the area clean you are also "sanding" the surface, prepping it for the primer/paint. Once you have scrubbed everything clean you use the DX330 for the final wipe down prior to primer/paint. Other chemicals/solvents I tried did more damage than good, so it was worth the $32.00 a gal for the DX330. And it should not take more than a gal. to do what you are doing. MN. Bob Yahoo!
