Hello. I acquired a set of staggered 18x10/9 Chrome FR500 rims. The left side wheels were pothole damaged and are at a shop for repair right now. He claims he'll be able to restructure the lip of the wheel by grafting new section and welding just like many wheel repair shops. The wheels have various flaws including chrome pitting, gouges and curbrash. I am going to sand off the entire face of the wheel through the chrome down to the alloy. At this point, can alloy be polished up to a mirror finish like an aluminum rim is capable of? I understand that it is a lot of work, but I am willing to sand in stages to attain the desired finish. The rims that have pitting will be filled in with metal filler like JB Weld, and sanded down to an even surface. Will these spots polish up like the Alloy that is in the rim, or will they be unable to attain the same finish? I realistically don't expect to be able to polish JB weld to a mirror finish. I'm looking for peoples experience and honest opinion. I am being very realistic about this, but I want to know if it is at all possible to achieve the result from an Alloy rim. Keep in mind I understand they are not aluminum.
