We all know that vans rust. I don't see many T5's with rust on them but see a lot of T4's suffering around the wheel arches etc and with our salty roads I'm guessing that eventually rust is an inevitability. My question is Are there preventative measures we can take to keep our vans nice and solid?

T5's are galvanised, T4's aren't. Never seen rust on a T5 that hasn't either been from accident damage or a previous bad repair.

Ok, so just looking through garage and have found a couple cans of Bilthambers equivalent to waxoyl, Dynax S50. It's great stuff, easy to apply and doesn't smell as bad as waxoyl either.

Anywho, I know that the T5 is galvanised but we still live in the uk with salt and plenty water on the roads so I thought I would do search for rust prevention. My last T5 (08 plate) did have a few localised bubbles around both rear arches right in line with where the inner and outer panels are pressed together. Also, I have seen rusting around handles on back doors, barn and tailgate so these are the areas I am gong to treat (I have good access at the moment to the inside of the rear arches).
Next time I have the liners off in the front wheel area, I will Clean and treat the lip,on the inside of the arch.

So, does anyone have any rust points they would care to share for me while I can actually be d to do this? Plus it will help for future people should the do a rust prevention search on here. Are the T5's now over 10 years old showing common weaknesses in the galvanising? Etc etc.

Thanks in advance to any replies.T:

Thanks for response. Have used dintrol before but much prefer S50 because it's Easier to apply. Both give very good results though. Not come across epoxy 121 though so will look into that.

But I was meaning does anybody else have any areas of rust to point out that can be treated on mine to prevent them happening in the future.

Remove your wheel arch liners and clear out loads of muck that has made it's way behind them, then have a look at the front arch lips. My 2008 had some rust starting to take hold there.

I second removing rear wheel arch liners and some of the plastic under guards,wet mud can linger here for months on end. The area above the rear shock mount is a good place for it to start.

For reasons I don't want to go into (had enough of constant breakdowns at the moment)I had to remove the door cards from both barn doors. There is definitely rust inside at the bottom, where the two panels are pressed together. Def gonna get some Dynax in there!! Might do others doors too after seeing that.

Both my barn doors have bubbling paint and minor rust around wiper apertures and this is on a 59 plate van. :eek:
Had some minor rust on sliding door hidden behind the front door seal from halfway down to bottom. Rubbed it down, applied rust eater and several coats of primer and top coat and has been fine ever since. Otherwise van is spotless (ish)
Going to remove wipers as I never use them and ask local bodywork specialist if holes can be welded up as I don't fancy having rubber bungs to cover the holes with potential for them to rust again.
Imagine it's a waste of time to approach VW with a complaint about the rust??

Hi I own a 07 T5 and have one or two rust spots on it!!. The bottom corners on both driver and passenger doors. Also on the leading edge of the sliding door where it meets with the fuel flap. The sliding door was touched up last summer and the rust is starting to reappear again. Personally I was going to get it touched up again but this time I was going to try some (helicopter?) tape I used on my MTB to see if it helps.

I thought VW vehicles had wax corrosion protection sprayed into the box sections doors etc. Not a spot of rust anywhere on my 2004 T5 & hope it stays that way.
