Advice sought

[kak577]

Off topic a bit so sorry, but....

Got an old citroen saxo, just got it through an MOT with more welding for corrosion than my wallet would have liked. Looking at stripping the old underseal off, giving it a rub down and a lick of paint and then some underseal.

Here's what I am thinking of doing, can I grab some advice please as I am competely new to all of this. Also trying to do it on a budget, the whole aim is to get it through just 1 or two more mot's so doesnt have to last for decades! Plus I am poor now :P

Was planning on doing the following:

1) remove underseal/rust (might not be able to get all the way back to clean metal, but just until it stops flaking)

2) Paint with zinc 182

3) Paint with red oxide (namely as I can see if I have missed a patch as its a completely dif colour to the zinc)

4) Hammerite in white (got an old tin lying around so was just going to use this, again dif colour so easy to see if I have missed a patch)

5) Probably Hammerite underseal over the top as I have half a tin.



So really, just want advice to make sure I can add the red oxide over the zinc 182, it's really only as its a diffrent colour so I can see what I've painted. Tried to paint the white hammerite onto the 182 on a bench and struggled. I'd image it would be worse underneath a car!

TBH if you just want to see it through a couple more tickets, I'd just lay on good coats of the red and forget the zinc, save the money. So many adhesion problems with it, but folk do seem to like it nonetheless. Regardless of that I can't see much point in it here, or the hammerite either really. And if you slap some wax or something over it, there's even less need for it.
I'd slap on red plus wax or schutz and have a nose at it now and then, check it's still OK.

Want to get something onto both sides of welds/repairs ideally. Primer and schutz or cavity wax or whatever.

So red isn't what it used to be, like so many things. But I've put some on Landy wheels and left them outdoors for 8-9 months over winter and nothing came through. It does contain zinc phosphate. Was just cheap Rustins red.

Thanks for the advice. Sorry, should have said, already have an opened tin of zinc 182. Also I live right next to the sea, so would that reduce the lifespan of any of the paints mentioned greatly?

id go with 2 layers of one of the primers...should provide the best chance of it working rather than mixing brands

never liked hammerite ..if choose some diy store enamel or chassis black myself , or some rattle can shutz

Wack the 182 on then, I believe it needs a rough surface to stick to, and it needs (light) sanding so other paint can stick onto it (will help waxy glops too) - not used it though.
The sea air will find any bits not protected, just make sure it's got a good load of primer & wax/schutz/underseal on there. Any bits not covered, rust can start there and creep under paints etc.

Might be worth seam sealing some welds actually, depends what was done.
