Door runner restore
Discussion
Hi,
I have a UK Renault Master MK3. The side door runner is corroded and preventing the door slide from working smoothly. I will look at improving the side door slide mechanism but my question is - how do I paint the slide\runner to have a smooth but tough finish again that will last?

Thanks in advance

You have a couple of choices, the best is to buy and fit a new runner.
If thats not an option based on price etc, the silver option is remove that one and get it shot blasted and powered coated at a local shot blaster, they won't charge a lot, a set of 4 wheels is usually only about £60.
The DIY bronze standard is rub it down (ideally off the van), get rid of all that rust, treat it with a rust convertor (Bilt Hamber Hydrate 80) then prime and paint it with an epoxy or an enamel, however the weight of the door will still eventually rub it through. If you cover it in a marine grease it will help a lot
Your cheap option is clean all the rust out and treat it with a rust convertor and then stick a strip of helicopter low friction tape in the runner, I think UHMW (Ultra high molecule weight?) tape is even better, it creates a low friction surface for the runner to slide along, its designed for conveyor belts etc, but the valley needs to be rust free for the tape to stick to it otherwise it will just scrunch up, but if you can get it to stick its a decent solution.

Thanks for guidance. Appreciated.
So I am not familiar with powder coating. Will this create a tough smooth surface? Will it take longer to rub through than just recoating with epoxy and 2K paint?
Thanks
You cant powder coat yourself, a decent shot blaster or powder coat factory will advise but yes its a lot tougher unless you crack it then it splits and allows moisture in so it rusts beneath.
It usually quite cheap, look up a local factory and give them a ring, as I said, for suspension parts or wheels its a cheap solution but you would have to take it off the van to take to them, otherwise clean it of all rust, leave it bare and cover it in marine grease, or use a tough enamel or epoxy and let it set then put a UHMW tape over it designed specifically for things to rub against, its easily available on Ebay, but it won't stick to a rusty surface.
Lots of choices depends on how much you want to do yourself and how much a replacement runner is?
