Treating rusty coil springs

[PositronicRay]

While I fit new lower control arms should I tackle rusty springs?

I'm more concerned with preservation than aesthetics. Springs are quite rusty should I wire brush and use a rust convertor (I've 1/2 a bottle of hydrate 80 in the garage) and paint with something or other or just not bother?

Blasting and powder coating sounds expensive, new ones are only £50 each. It was mentioned as an MOT advisory.

I had that as an advisory a few years ago because the paint coat had started to fail on the top coil. It turned out to be only surface rust & I just cleaned up and covered in waxoyl, it was never mentioned again.

This sounds sensible.

I've other cars I can use so being off the road isn't an issue.

New springs (Sachs) are only £50 each so I could replace them but the car sits level and drives nicely. I think I'll go with wire brushing and waxoil.

I'm replacing the control arms because I noticed a knackered ball joint the other day when fitting new dampers. If I have to do the springs @ a later date it's no biggie.
