Wanted to share...
I successfully painted my MK4 as a first timer (not counting spraying tractor & implement enamel through the Harbor Freight purple gun). I had a small drip/run under each tail light and a small sag & run on the right side of the body near the vent cutout.
I had a large test hood that I did some test spraying on. On one area of my test panel, I got a big ugly sag with multiple runs. I decided to test my hand at removing that defect and cut/polish that section of my test hood.
I purchased the Festool Paint Nib & Run Remover (Festool part #497525 / 3m part#29925). It was expensive for a glorified razor blade but I have to say, this thing is awesome. It is nearly idiot proof and it does a fantastic job shaving down nibs and runs. I highly recommend it if your reluctant or worried about using a razor blade like I was. It is WAY better than the nib files and Unigrit Blocks.
Then, I tried the glazing putty method on the sag. I used Dolphin glaze over the sag (about a 12" long area) and started sanding down the glaze putty with 220 grit dry. Once I was sanding into the sag a little, but still having complete coverage of glaze putty surrounding the sag, I went to 320 dry, then 600 wet. I sanded all the putty off with 600 wet. Then the entire area of the panel up to 2000. CSI CeramX with a rotary and their blue wool pad and then their red foam pad.
Amazing how well the area turned out. Im astonished how such a BIG ugly run/sag is gone! I have been nervous of all these steps doing the body & paint, but the cut and polish seemed as nerve racking or more than spraying clear coat. Granted, Im not doing the car yet, but my confidence with cut/polish and the rotary has deffinitely gone up a notch or two.
Hope my post helps someone else in the future.
