The best way to do this really is to grind or sand as much of the rust out as possible, any cure rust product will eventually re rust, and all they are is a phosphoric acid base in a polymer sealant, which isn't the easiest to sand back and overspray. Try a paint factors and get some advice from there, you may get a phosphoric acid etch which you once you have ground the worst off, leave on for a while then wash off dry and prime with a rust inhibitor primer. I used to work in a lab so had the luxury of neat acid, and have used this method with some good sucess

------------- Are you sure you couldn't squeeze anything else in love ?
Yes Thanks Jon & others. I was working on a plan to grind out the flaky stuff down to a firm base then use the likes of fertan to stabilise prior to priming with something like Zinc 182 anti rust primer.
I have used Jenolite over the last couple of years but due to the fairly superficial application the rust eventually has it's way. Looking this year to spend more time on it.
The ultimate solution is of course to cut out & replace.

The VW caddy pickups look great, there is a big following for customised pickups.
You are quite right. There is a big following for VW Caddys. Worth much more now than its original purchase price. sadly the current trend is to "slam" them. Our is still standing.
