Call me sad, but I've been looking at the rust on my rear subframe. It's horrendous, all the galvanising has disapeared where the parts get exposed to the elements. Such a shame, with the rest of the chassis being aluminium. I was thinking about shotblasting the rust away and painting it, but got the opportunity to buy a mint subframe off Ebay. As it's mint, I would like to keep it that way. Has anyone painted theirs, and what did they use?

I painted mine with high temp silver paint, the stuff used for exhaust manifolds etc

not the easiest parts to swap over though

WOW, love the whole thread Vocky. Nice to see your suspension looked just like mine does at the moment. Not fitting my Nitrons to a pile of rust, so will be busy shot-blasting and painting in a week. Did you brush or spray your parts? I have a compressor and filter, just no gun yet!

I'd use either: A can of cold galvanising spray or red oxide paint first

Then cover with a heat proof paint

Is the rear subframe classed as part of the chassis - the vx comes with a ten yer warranty on chassis corrosion The galvanized finish of the subframe should last at least 10 years, usually more toward 20

I was told that sand blasting the galvanised Subframe coating off saves over 2.5kg+ in weight too (so I've been told!) If my car was in bits, I would have it done, but, I wouldn't strip the car down just to do the subframe.

Why not get it powder coated or try asking cam coat what they recommend. HTH?

Lots of warnings in other forums about powder coating chassis and corrosion appearing under the powder coating.

Thinking of going with epoxy mastic:

If you're applying straight onto the existing partially galvanized surface you'd be best using something like this first

the tvr boys, waxoil and then hammerite their rusty bits. maybe a slight variation could be a red-oxide primer and then hammerite.

i suspect the original galv would have been hot dipped but if you prepped the subframe and then galvafroided it it may be ok?

Any chance you could post up some pics of the problem areas
