Had to shift my attention away from the TT floor pan and over to the chipping paint around my wheel wells. It's borderline too cold in the evenings for the paint to cure so I grabbed some supplies from a local body shop supply store and jumped in like I knew what I was doing.
I took my time getting going and was running out of daylight and warm weather so I didn't fill and sand the blemishes along the rim of the wheel wells (pulled them a little to help prevent rubbing) like I had wanted to but I got a pretty good primer base under a few light coats of paint. That should keep corrosion levels down at least.
Both sides were in disrepair but here's a little proof on the driver's side...
Step one - admire the chipped paint & oxidization...

Cleaned up the surfaces with a flapper wheel and then some sandpaper...

Masking was really the worst part of the event - used a couple 2x4's behind the open door as newspaper backing...

I used an etching primer that was recommended by the supply shop, although someone else suggested primer surfacer?...

And finally - admire the VW supplied touchup paint that doesn't match...

I don't see the point in getting too particular with the finish when the colour doesn't match, so I'm not going to bother with a clear or anything else really... aside from wet-sanding to get rid of the ridge where the paint and tape met. Good enough till I can go widebody and then the fenders will be getting cut anyway.
