I have an old "powered by ford" vavle cover...I was thinking of getting that chromed...will that work?
can I do that?
"Yes,
but..."
please consider that cast aluminum alloys tend to get soaked and virtually impregnated with engine oil when operated. I found
very thoroughly cleaned rocker shaft pedestals and timing covers still seeping oil after some months of storage.
Platers can, or at least
should take care of that with high strenght solvents like kethone and special cast-alloy-friendly hot tanking, but I also know of some platers who were driven almost crazy when supposedly clean parts started bubbling and bleeding oil traces everywhere during the plating process, contaminating the whole plating bath.
Also, not every cast light metal alloy is equally suitable for chrome plating, depending on other metals and contents.
With those given difficulties, I´d just go crazy with progressively finer sandpaper, wet sanding and final buffing and be fine with that. There are a bunch of care products for polished aluminum avaialbel, of which nevr-dull and the like are the least abrasive.
On the other hand, if you can really find a reputable plater interested in business who won´t drain your wallet, go for it and consider yourself lucky not to live in Old Europe, where the few platers are dominated by treehuggers, and therefore charging considerably big money.
Just keep in mind that scratches and damages to the chrome layer are kinda hard to get rid off.
Then there´s ceramic coating finally (cmpletely unavaiable over here), I remember a dude from the forum who had some of his cast alloy stuff ceramic coated.
