Looking for DIY trim restore tricks

EZ-Off classic yellow without the lemon scent was only one that worked for me, other than straight red devil powdered drain cleaner. That stuff will eat the AL too. Just dip it in for about 15 seconds and then pull it out, rinse and see where the anodizing is starting to fade. I actually pinholed a thin section on some 65 headlight bezels with the lye. I have a very light hammer that I polished the face of to a mirror for my bezel restoration. you need a shaped backer when tapping down the high spots. A drum stick or other blunt object works but will make its own little craters but it depends on how hard your tapping it. even the back of a large kitchen spoon is enough to smooth the slightest bumps.
