Auto body repair & detailing: truck body repair, gmc sierra, quarter panel

Question
I have a 94 GMC Sierra and the salt is just eating the sheet metal up.I would like to replace front fenders and maybe one side of bed. I would appreciate any info. before I start this job. Also can I apply replacement panels to say the cab corner without a welder?
Thanks,
Dave

Answer
Patch panels can be glued in place with a special adhesive.The fenders are bolted in place and easily changed.The quarter panel is the tricky part,you need a welder for this.You could put on patch panels with glue also instead of a whole quarter panel.Eastwood restoratin supplies has everything you should need.
