IRONBLOCK Dave, I got my set for F R E E -just had to pick them up! I was still a school boy then so it must have been 1982-ish.

I remembered seeing this thread about mag wheels and may have to try some 'Gibbs' on my polished MM wheels to tone down the unpolished areas a little; may even try the graphite as well.

IRONBLOCK I've had a set of MM's between two spider(s) for about 37 years now. They were left outside for a year or two by the previous owner and they were very nasty and corroded. They were just like the gnarly Pantara wheels someone posted but they cleaned up well and have had no issues other than a thin black film that needs periodic polishing to remove. I suspect these wheels must have a small amount of Mg in the Al alloy.

When new these wheels came with a chromate conversion type of coating that offered some degree of corrosion protection. I have one 'spare' (that I am using) that has almost always remained in a spare tire well and the thin conversion coating is intact and exhibits a slightly gold-ish tint.

Sometimes powder coating Al/Mg wheels can result in undesirable side effects (blisters and corrosion) -if the wheel is not properly prepared, coated and cared for.

i have vintage campys and cromodoras and bbs e50 mg wheels in dry heated storage. they show signs of corrosion on the unpainted faces just sitting indoors. if the MM really are mg its content percentage must be minuscule

never the less 7x14 MM are to die for!

a pretty darn easy way to guesstimate the amount of mg in the wheel is how dark untreated areas get. if its has high mg content it becomes dark grey from exposure like the sexy gta/gtam autodelta mg valve covers and bellhousing.

you can see how dark they get...

DPeterson3 Definitely belong on a Montreal. I’d cross-post to that forum.

davbert they are aluminum
05-10-2019 05:41 AM
Craig_m67 Crikey! They should be in the women and Alfa’s thread!

I’d grab them, but I don’t need the tyres.... (and I’m in the wrong country)
