Let me start by saying I've been in the body shop business for 27yrs. I can tell you silvers can be difficult to match. We use PPG DBC. I decided to rid my front bumper of stone chips so I took it off stripped it, acid cleaned(DX 533), gave it 2 coats of DP epoxy, lightly wet sanded with 1000 grit. Mixed up 936 and it was way off, way too course. So I did what any intelligent Porsche owner would do, search pelican.... I didn't find anything on formulas that were a close match so I went to my variance deck and found a BMW formula code 244 chip looked close so I sprayed a test panel, extremely close. Not sure how close a match glasuit 936 would be but I figured PPG is more readily available for most. Hopefully this will help someone else save some time. BTW my Porsche is a 86 with 59000 mile so the paint is in nice shape, mileage and year may make a difference on color match but its a near perfect match on mine. I took a pic using sungun sample not exactly flat to gas lid, rt side 936, left 244
