In preparing the rear windshield for installation in my '74 GTV I installed the seal on the glass and then carefully pressed in my new Classic Alfa aluminum trim. I could hear the cracking as I pressed it into the seal in certain places- usually the curved sections. (see picture) I now have visible crazing if not cracking of the anodizing. Is this to be expected? I have a good plating shop nearby that can re-anodize and I am thinking I need to do that but how do I prevent that from happening in the next installation?
