DIY rust removal

[annemarigold]

I've seen the Rust directory and searched but not found quite what I'm looking for. My new purchase of a 1998 Friendee has some rust spots that I'd like to deal with. I cannot afford to pay someone. I've googled and there are loads of "how to" websites but unfortunately they contradict one another. For instance some saying you must use a grinder others saying whatever you do don't use a grinder. I'm more concerned about removing the rust as safely as possible and stopping re-occurrence than aesthetics as we plan to paint the van in the medium term. Can anyone recommend a site with step by step instructions and using easily available products at a reasonable price? Thanks Anne

Hello Annie
I would suggest looking on you tube as you can often see the before and end effect.
The trouble with rust that unless you fully remove it, it will come back eventually. I have tried hammerite rust killer, which you paint onto rust which is then suppose to have a oxidation effect killing the rust, but sadly it does not work and the rust came back.
I have found you really need to remove the rust as much as possible, for me rubbing down with wet and dry paper of varying grades was the way to go, rubbing down to clean metal is essential or replacing the rusty metal if possible. I have used a grinder in the past but that's really for larger areas as they can be very abrasive and aggressive, plus they tend to kick which could result is damage elsewhere. I use a dremel for smaller areas coupled with a grinding attachment. If a hole is created this can be filled using filler or fiberglass. Although filler must be painted over as its pourous if left for anytime.
Good luck, as with any older vehicle the rust worm will always make an appearance, just keep on top of the rust spots and learn best techniques as you go.

Thanks Geoff. I was thinking instructions such as what sandpaper to use. How wide to sand beyond the actual rust spot?

[g8dhe]

Where are these rusts "spots" ? What size ? Can you put some pictures up ?

[annemarigold]

OK will do a bit later. They vary.

These are the worst spots. There are a few much smaller ones too.

Thank you Roy 748 I take note. I've made a start but weather has now defeated me.

Hello,

I'm new to this forum - but am also looking to embark on some DIY rust repair. We have a 2002 Bongo with similar rust spots appearing.
How did you find doing it – did you use a dremel tool. I'm keen to attempt it myself as have been quoted between 600-1000 to fix at a body shop!

Any advice appreciated!

Make sure that the spots your referring to are only surface spots, provided they are then using a Dremel or simply suitable grades of sandpaper to remove the blemish and smooth the surface prior to undercoating and then top coat and if needed a clear coat.
The problem comes that a lot of rust problems are not surface rust but rust from behind that has eaten all the way thru the metal to cause a blister behind the paint. Its then that a bit more serious work is required to replace the damaged metal before repainting.

Thanks g8dhe –

This is what I'm looking at. I'm going to try around with the wheel arches and see how I get on.

The bubbling on the arch is from the rear, the others (as far as one can tell from photo's alone!) seem to be surface abrasions with the rust on the outer surface.
