Can I treat slightly rusted coil springs with Waxoyl

Corrosion isn't the issue with springs, it's pitting. If they're heavily pitted then they'll fail long before corrosion rots them.

Isn't the pitting caused by corrosion?

A very interesting article here:

Real science, not uninformed conjecture.

That's why the ends of decent springs have plastic sleeves on them.

I've just had a MOT fail on a broken front spring, but both fronts were replaced 3 years ago. No obvious damage the the wheel, tyre or suspension at that nearside wheel. 3 years seems too short for a spring to last, if there's no other obvious damage cause. I think the materials, size and suspension design are suspect but without other similar instances difficult to prove.

If you can't remove the rust completely and apply fresh paint, your best bet is to use a decent anti-corrosion formula like ACF-50 that is proven to stop and prevent further rust. It does need applying at least yearly before the winter sets in though.

You beat me to it, that's what I do. It is oily though, so don't do it just before an MOT, or it might look like you have a leak. If things are clean and in good shape though, then you might want to try something like Atom-Mac from Bilt Hamber. It's dliuted in water and so not oily but, as the water evaporates, it leaves a rust inhibiting coating.

A failure at 3 years would have me questioning the quality of those used.

A lot of aftermarket parts are just crap.

OEM would last longer, but usually cost a lot more.

Well I brush a bit of grease on where the powder coating comes away. It might just be a short delay of the inevitable, or completely pointless, but I feel better having tried!
