Aluminium Polish

I got some weak acid on the aluminium engine case of my Bull.. I have a dark gray blemish about the size of a cell phone on the case...I want to bring it back to its luster..
I have some 'mothers' metal polish but not really happy with that.

anyone have any 'recommended' aluminium polish?

I know its not "Husky"....but it's 'vintage'

The best I've ever found is autosol (comes in a toothpaste type of tube), just put a little dab on a cloth wrapped around your finger & do small areas at a time, you'll feel it go from slightly rough to mirror smooth, then with a clean cloth, buff it.

By chance is the case anodized, painted, clear coated aluminum?

If it is, gonna be a tough one!

thanks Ruffus I'll look online for autosol....
But still open to suggestions...

none of the below... just a polished cast aluminium case..

Found at better Harley shops everywhere

x3.

Brilliant for cleaning chrome, stainless or any metal. It's literally a metal polish.

Good luck!

I use Blue Magic polish. Advance Auto, and I think Walmart may still carry it. This stuff always gave better results on the polished bits of an old Triumph Bonneville I had vs the other redily available polishes. It has a finer jewelers rouge than many other brands

tough decision gonna get both... LOL..

AUTOSOL -best by far

I went to 3 bike shops..2 of the biggest Harley dealers...no autosol!
ordered it on the phone...

Autosol --Aluminium polish as they said --

Autosol also make a Plastic scratch remover polish and a metal one --

Going to need a lot of elbow grease --hehe --but works well

You might want to try a 1000 grit wet and dry emery paper first to cut through the discoloration - Aluminum is pretty porus and it may take a while to get back to bright metal with the polishes mentioned above (they lack serious abrasive cutting ability which may result in hours of polishing and no result) most of those polishes are simply a grit compound held in a paste - equivalent to a 3000grit emery paper (approximately)

I would test a fine grit paper with plenty of water on a spare peice of alloy casing and then once the emery paper is slightly worn in and you are sure that you are not going to damage the surface attack the real stain.

If you wanted to do away with the pastes althogether then fit a cloth polishing mop to a drill and do the final poilish using a hard polishing compound such as a rouge - or alloy specific polish compound (all this can be found at Home Depot)

The advantages of the right wet and dry paper followed by a drill powered polishing mop is that you can cut back metal and bring back a high or low finish polish to alloy very fast...

Avoid trying to repolish anodized or clear coated surfaces - giant head ache! (as noted by others in this thread)

If it was as easy as the side of the can says it is to polish aluminum, everyones aluminum would look like chrome. To fix and polish what your talking about you need electricity. This is a great kit. And by using your drill, you can leave the cover on the bike. Although it would be a lot easier taking it off and doing it on a bench.

wow I like that kit.. To be honest with ya... the stuff at home depot is VERY limited or non existant. I am gonna try 0000 steel wool and some other stuff I got "Gords".
