Here is a photo of my O/S/F wishbone bush mounting point. It has started to rust. I want to keep the car for as long as possible.
Shell I get it welded up or just wire brush and paint it before putting the new wishbones on?
Thanks

Hello Rob, its been a while. I have no idea how I managed to forget the photo link. Here we go. ::) :y

I'd say that's 'fine' I'd give it a good brush (ideally with an angle grinder and wire brush attachment) then a paint with something like either Rustbuster 121 or hammerite. NOT waxoyl, as this has the habit of trapping rust and moisture underneath. Fine for perfect unrusty metal, but never, ever anything with rust already present.
Of course the best solution is always cut out and replace. But it'll have to be done with high skill, otherwise you're going to cause yourself headaches come chassis geometry time. (or, stupuid as it sounds, even refitting the wishbone itself. 1mm out could well be enough to make refitting said wishbone a beetch.) :y

Mine was worse than that when I bought the car six years ago! There's nothing to weld, but a quick wire brush and coat of paint is more than good enough.

Do I need to use a rust converter or does Rustbuster 121 contain it already?
Hammerite has changed the formula they use to make it more compatible with other paints. It can take a long time to cure depending on the thickness. That's what the reviews are saying. Not tried it yet.

What paint did you use and did you use any rust converter?

Me? I left it well alone, and spent the time doing something important - beer, day dreaming, chocolate, sleeping something like that. IF I was going to do this job, I'd use a wire brush on the angle-grinder, epoxy prime and brush on a coat of 2-pack chassis black. Hammerite is useless since they changed the formula(it was mostly marketing wank before), and I've never been convinced by rust converters.

I must admit I've never had any success either. The rust always wins.

Is that the wishbone bush housing as it looks like the bush outer casing. If so remove and fit poly's, job jobbed. :y

Yes it is. Definitely putting poly's in. :y

The 121 isnt a rust converter, and agree with above - they never work, they just don't. Nearest I've come across is acids that physically eat away and dissolve the rust, but 'converters' well, I've used them on the chassis before as a 'well, can't hurt, better than nowt' approach. The 121 is basically what Hammerite wishes it was, it's a two-part epoxy, think of it like runny black Araldite :-) sticks like glue, and forms a stove-baked on coating. They also do other 'direct to rust' options. Check out their website for more info. Personal experience of their 121 epoxy, and would give it 100% :)

Thanks for the info. I'll give the 121 a go. I got one of those 1" wide sanding belt tools to rub down the rusty parts back to bare metal as much as possible on the front chassis legs. The 121 would be a good solution to protect them in the future as well. :y

They do do a 'direct to rust' paint which I suppose is really what Hammerite is supposed to be for, too. I'll be using this on my rear wishbones when I get round to it. :)
