Rust cure, can it be true?

Post by **PAULJ** » Sat Mar 01, 2008 7:08 pm

Hi all, im sitting hear looking through the FROST catalogue trying to decide what to coat the restoration job in to cure and prevent further rust. This is surface rust and those hard to get to places with the wire brush.
FROST seem to do lots of products that promise this but do they work?
Can anyone recommend the best.
Cheers
Paul

Short of replaceing the rusted steel. Bilt Hamber kit is the best currently available. If on a tight budget Hammerite #1 Rust Beater Primer is good. Loctite 7503 Rust Stabiliser is good for surface rust, after removing any loose rust with good sand or wire brush.

Most just seem to cover the rust and stabilise it, rather than remove it. Acid seems the only way to get rid of it. I've found Jenolite to be pretty good, with wire brushing in between applications.

Frost are well good at marketing in thier catalogue on lots of things like that.
(not to say though if i was wealthy would have a garage full of stuff from it)

Rustoleum do a decent one, hammerite do too. Both similar products, best guess is its an acid & PVA mix, the acid to 'neutralise the rust, the PVA to seal it airtight and give a good key for the primer.
If you get it on your fingers it blackens them just the same as using moredent solution (the commercial metal primer particularly for fresh galvanizing or bright steeel - blackens it instantly to give a primer / undercoat key - moredent solution is phosphoric acid)

Used a tub of rustoleum recently that had been in a shed for a few years, fortunately never got round to finishing the job which was just as well because new steel went rusty in 2 weeks which i wouldnt have seen if it had been painted over.
Best guess is that the product got frosted whilst in the shed rendering it no good.

Theres a rally good thread on here i cant find and a few peeps have treated various bits with various products and left them in the elements, some really intersting results.

Yes, this is the only way to stop rust. Either that or cut the rusty metal out and weld new in. So called "converters" are rubbish. They only convert the top layer, try scratching the "converted" rust and you'll see more rust underneath.
