Doing a 6 engine.....I would like to make alternator support housing look original.
I do not want to paint. Any knowledgeable suggestions..
A. To clean up
B. Finish so protected
Thanks
Problem is it's magnesium, if you don't coat it it will look like shit in about a month.
Some guys blast it clean (fine glass, walnut or soda) and then clear it with a semi-gloss clear or just spray it with Gibbs penetrant, wax, etc.
With the gibbs or wax you will have to reapply often.
In a /6 you barely see all except the very top edge, I wouldn't obsess over it. I just painted mine close to the natural colour.
