You added crosslinker to the stuff, and should thus find that the
primer is impervious to anything but paint stripper. Any cleaner that
appears to soak into it will evaporate out. I think the safest is
rubbing
alcohol, and it has caused me no trouble with either water- or
solvent-based
topcoats. More problematic is dust, which causes fisheyes. If you're
not
going to clean them again upon arrival at the shop, I presume you'll
be covering
with plastic?
