I hope it will polish as well as the surrounding area also, so I don't get a ring there.
This is the test I did, filed it down and from what I can see it looks the same as the alu.
Have a broken fastener lip on the backside of my SE tailpanel also, gonna try to solder on a piece there
if I can find a thin piece of alu.
