ok you may not want to hear this but i promise it will get ya what your looking for
go get some tripple 0 or 0000 steel whool your gonna have to get to good alum
just pretend that your gonna polish with the wool
it will turn black,that good cause the more black you get out of the alum the better
after some rubbing will start to see reflection next i would use some fast cutting rubbing compound it will take out the fine scratches the steel wool made again thr more black the rag or buffer wheel gets out the better
after this stage you will notice huge differance then what you started with
now you can hit it with some mothers alum polish but do small spots and get it to mirror shine before you move to next spot always try to just work a spot the size od baseball and prob go over that same spot least 3-4times before moveing on lots of junk t shirts will be your friend
you will get a shine you can read a paper in but lots of elbow grease
the powerball/drill not gonna help till you get the high luster first
remember the more black you get to come out of the alum the better
dont be stupid and try clearing the rim cause will take the high luster you just worked for out and leave the never dull where you found it
