I scavenged this Porsche GT3 cup front rotor from a garbage can at Sebring. I want to clean it up and hang it on the wall in the garage. What would be the best way to clean it up? And, once I do, should I spray it with some clear polish or something to keep it from rusting?
CLR and clear coat spray paint
As long as it's clean, clear coat will stick and protect it from rusting. You just have to decide how glossy you want it and pick the clear coat accordingly. I did this with a rotary engines rotar after at lot of soaking in simple green (obviously a lot oiler then a brake rotor) and it worked out great.
Why not just have a machine shop do a cut on it? It'll even out the wear area and get rid of the rust. Then clear coat it
Evaporust 1st Don't machine it will to smooth you want the lines from use right? Wash with water and dawn, bake in oven then clear with a satin clear.
I'd hit Michael's or other craft store /rockler hardware for a clock kit.
engrave the hat w/ Sebring 2016 or sumthin' anyway
Agreed that I don't want to remove the wear. But I do want to remove the rust. Could I hit it with a wire wheel? Abrasive enough to knock off the rust but preserve the scars?
Why bake it in an oven?
Any abrasive will remove some of the patina. I would use only a chemical rust remover. Alternatively you can use a used brake pad and "sand" away the rust. Thus preserving the patina as best you can and remove most of the rust.
From where it's rusting - if you just install it in your GT3 cup car then do a couple quick stops it should take care of most of it.
The rust will go away if you soak it in a bath of white vinegar.

LOL. Of course!

I'll try that first. I have a jug out in the laundry room for soaking purposes already.

X2 on the vinegar trick. That stuff works great!
I just did a coat of wax on some camshafts I used for an engine table legs and they haven't rusted in a couple of years. The wax shouldn't wear off since it isn't exposed to the elements.
I have used vinegar and salt in combination it works faster than just vinegar alone. Just spray it down good with fresh water afterwards and dry. When dry wipe it down with vegatable shortening and bake it like you are seasoning a cast iron pan.
You can use the left over ingredients add thinly sliced potatoes and make some salt+vinegar+asbestos kettle chips
That's a super cool score! Guess I am going to have to go dumpster diving in the pits now!!

Dry it and keep it from flash rusting in the vent holes plus it will warm it and cure the clear faster if it's warm not hot when sprayed.
