Anyone out there have a quickie link to seam rust fix; like how much
POR to order, how much of their putty to do all seams, and whether
part of the job includes resealing all the fender wells.  I still
don't see how the rust gets back in there except from the
outside.  Gonna bite the bullet and do this project in a week or
so.  Any tips to make this easier on a 90 GL?

TIA
