Preventing rust from spreading on chrome
 

Hi folks,

I noticed a few spots were rust is starting to form on the chrome lugs and I was wondering if there was a way to treat it before it advances further. The pictures make it look worse than it is.

Thanks,
Mike

Phosphoric acid will convert the rust to iron phosphate, a dark grey material which is a good base for paint, might help in the logo
but not for the lug. The rust has destroyed the chrome plating and there is not much you do about that. FWIW coca-cola, pepsi
and similar cola drinks are dilute phosphoric acid solutions and work well as rust convertors. You can look at it on youtube,
and the diluteness would be less likely to damage surrounding painted areas.
The problem is that the rust is occurring under the plating and absent plating removal you can just cosmetically treat it. Of course
mechanical removal also works but is detrimental to the paint and shiny chrome.

You could crumple up some aluminum foil, get it a little wet with water, and gently scrub it off. Use lemon pledge or a car wax to help stop any further damage.

I use a Brillo or SOS pad. Get it wet and it won't scratch the chrome, but will remove the rust.

So no matter what you do, it will keep rusting under the chrome, which will keep flaking off.

Yes, but if you put wax or light oil over it, you can slow the process.
