I have a lot of badges - all of them with varying amounts of blisters. I have hung onto these as technology marches on - they are repairable- but they are still perfecting the process the last I heard.
One option now open is to lightly blast them - remove the blisters - bog up any imperfections and paint them in Chrome paint- ( the new stuff that is a close match to chrome)I have seen this done - but I don't personally really know anyone that would go to such lengths.
So if you have no badges at all I can sell you some of the better ones for $5-$10 each -But be warned they are not perfect. At least the badges will match up with the factory holes. The repro ones when they used to be available didnt.
