Konstantine,
To be honest, I am not sure of your exact set-up. I kind of combined
various problems I have had with different automotive areas.
There should be no reason at all that you can not do this in the car
though. I think the idea is that you just want to fill in the pits, do
not build up over the stock surface. It may take a couple applications
and filings to get it just right.
