Lot's of ways to prep your fenders, a lot depending on what you intend to do with it when you finish. If you plan on driving it,vs. making a museum piece of it, make sure to use a good quality primer, get the fender welting or rubbers it calls for, and no matter what part of the country you live in, keep it as clean as you can. I'm not talking about the $5, sit the truck and let the robot do the work, but a good ol' fashioned truck wash. Bucket with lots of soapy water, and get down and dirty with the hose and a good pressure nozzle to get at the grime that builds up. Later, in the shop, if you can, get the air hose out after it's good and dry and blow out the vents, dirt between the rubber door seals, window tracks, etc. etc. You'd be surpirised how much damage the small sand and junk that gets into the creases along that area can tear up a new set of rubbers. What it all boils down to is get up close and personal with your ride as often as you can. First time you're in town and making a stop at any one of your stops, and someone says something good about your ride, you'll feel as good as a fresh lawyer with a waiting room that has standing room only.
