Hi, this is my first post. I went to the salvage yard today, and picked up some aluminum escort gt rims and some tires all for about 300 dallors, they were covered in dirt and i thought that was just dirt. Well, we got home washed em off. The tires looked fine but the rims had like... a crappy rusty like, the top layer of alum was eatting threw or something, i tried everything i could to try to get rid of it, washed em alot, and its really deep. I was wondering if someone had any suggestions and if i had to sand, or something like that could you please explain it to me.
Thank you
