I recently bought a Model F XT off of eBay with the intention of restoring it. It is in proper working shape and all the components are there, it just needs some loving. As I was taking it apart I took a nice look at the badge and realized it looked, weird, almost corroded. I own a Model M with a silver badge so I am familiar with that, but not the XT. If I recall correctly both are made of aluminum and the characters on it are not etched, rather printed on. What is odd, is that aluminum shouldn't corrode at all. This is what mine looks like:
I also attached the image if for whatever reason the above link expires.
I read here that the lettering can actually fall off when in a harsh solution. If anyone has any advice on how I might go about restoring this please let me know. Thanks in advance!
