[Vwdiesel] Anniversaries

[James Hansen]

Up here in snowland you can't even get one part automotive paint used at a shop, except for industrial finishes, nearly every body shop has phased in waterbased two part base-clear.  There was a time it had to be done by if I remember right, to get all low VOC paint being used.  Single stage is fine, if it was done right originally, usually is tougher than 2 part, but if it's falling off, it's to bare metal you go hi ho.  The only thing that might be an issue is solvent shrink of the underlying paint when it's redone, but if it happens, a re-do gets it the second time usually. Shrinkback is solvents from the new paint softening the underlying different paint, then drying funny, much later than the stuff that was applied... resulting in hazy finish, usually just a gloss defect around the feathered out areas where underlying paint layers have been exposed.  Usually looks like a topographic map around the repaired area done in slightly hazy.
If it's a hood that is needing to go to bare metal, consider a new hood.  It's way way way cheaper and safer than using paint stripper and all that work, which usually winds up in a nice heat distortion ripple finish anyway. Bringing a panel to metal, and refinishing is good for a 57 oval where there is real metal to work with, but on these new cars with thin metal, that is definitely the hardest and most expensive way to go about getting a finish that you may not be happy with.  

Congrats on the milestones.

I expect that next week, my 00 Jetta will make 400,000 miles.

I'm doing a little work on it as an anniversary gift (and so I don't get stranded somewhere.)  Glow plug harness, p/s pump, valve cover, etc.  One thing I've thought about is a little paint.  Due to a couple incidents, the front of the car, particularly the hood, has been painted twice and is now clear coat free.  I don't know whether it's low quality paint, incompatibility with previous paint, or just the fact that factory paint is simply better (the trunk lid is fine with original paint).

Could I just sand a little and paint/clear coat or do I have to go to bare metal to get a decent job?

Never worried what cars looked like before, just did barely enough to get me where I was going.
