POR15 is pretty good, but it's not the "end all" for rust.I've tried it  
before, and depending on where it's used it works great. I've also had some other 
problems with it, like "top coat lifting", due to it's properties.

Por recomends not using their product over "old paint", which means you need 
to use something else there, or remove it. In this kind of application, I've 
found PPG's DP90 epoxy primer works very well. You need to do the metal prep 
stage on the bare metal and rusty metal, but only need to "scuff" the painted 
surface. After you're done with that, standard automotive paint can be applied 
over it.

I think you can still do this, but you'll need to finish removing the VW 
paint from it. I've found the POR good for somethings, but not for others, and as 
a result seem to use the epoxy primer I mentioned above. I know how it works, 
what it'll stand up to, and what I need to do to the surface being painted 
before using it. It's really your decision on what you want to do. If you're 
comfortable with the POR, use it,if not don't. I've also found out that POR15 can 
be top coated with DP epoxy, if you use both within a 2 to 3 hour time span. 
This would probably give you the best of both worlds. : ) I hope this helps.
