Wheel Nut corrosion

Post by pianoman+88 » Wed 05 Jun, 2013 4:03 pm

Anybody have an idea how to stop my wheel nuts corroding on the exposed head? It really stuffs the appearance of the wheels having these little rusty blots in the holes.

cheers!

Are they chrome plated wheel nuts? If so, clean the rust off by gently scrubbing with 0000 grade (super fine) steel wool soaked in methylated spirits. Then wipe clean with a metho soaked rag and buff dry.

From there, you could try:
- spray painting them with a clear epoxy
- polishing with a decent polish such as meguiars next generation all metal polysh
- rubbing liberally with vaseline and then buffing off the excess (but make sure you leave a thin film of vaseline on them for protection).

Thanks, but they are not chromed. They are the original galvanised finish, and we've tried the steel wool, & polish etc. Latest thinking is have them satin nickel plated, then clear epoxied. Really, that should stop the problem recurring. Any thoughts?

Get them chromed, or buy chrome ones?

cheers

That sounds like a good bet. One other thought would be to paint them with POR-15 (or its Aussie equivalent, KBS Rust Seal) and then spray them to get the right colour - this would give a much thicker coating than nickel plating and would be more resistant to scratching or damage during wheel removal / installation.

If you haven't used KBS before, they do a sampler kit which has everything you need:

It's self leveling so any brush marks end up flowing out. You can also get the coating in a silver or grey, but it apparently doesn't like UV so you still need to give it a light coat of paint to keep the sun off and so you get a good colour match for your wheels. I've found the aqua kleen and rust blast is easier to handle too in a spray bottle - you just need a couple of those cheapie trigger spray bottles from the hardware store.

A much simpler method is to spend $20 and buy the lug caps (set of 20) in chrome for a perfect finish that wont rust and simply the fit over your existing 17mm lugs. They have a tool also to remove them when you want to remove/refit your wheel - see ebay link

I'd actually get them zinc electroplated or the new method of electroless nickel plating if you have a few $ spare.

They are zinc plated for a reason - the zinc is a sacrificial anode which stops corrosion between the alloy wheel and the steel hub / brake disc, so the wheel can be removed easily (corrosion prevention)

If you have ever seen what happens to alloy wheels and steel hubs when exposed to a little bit of moisture over a few years… it's not fun trying to remove the wheel.

This is why RACQ / NRMA roadside assistance carry sledgehammers. Ford's are particularly prone to having the wheels sieze on the hub and when you're stranded with a flat tyre and can't get it off…. well

I have seen plenty of MB's wheels do this, and yes we have a very big sledge hammer in the workshop..
