if you take off the rear door cards you will see the reno botch job, my valver is bubbling on the drivers side rear arch, but on the pass side its fine, if you look carefully you will see that reno have some rustproofing on the inside of all the panels, on the drivers side it goes up to just before the rear arch but on the passenger side the rustproofing goes all the way back to the tailgate, so my theory is that if reno had done the job properly in the first place on the drivers side there would be no bubblin!
Dang & Mikey get thoise rear door cards off and check it out, if it not been done proper get back to reno ASAP and get it sorted, but the only thing i will say is that reno could say that the car was MADE on (whatever date) and registered in Oct 95, if the manufactur date is before you may have problems getting them to do it. Sadly its too late for my 93 reg valver but i wanna get mine sorted ASAP.
