Chemically removing IC identification??

[gijim]

I was wondering if there was a way to chemically remove the identification off ICs, as a method to prevent (discourage) reverse engineering? I know I could sand it off, but that takes time, and just looks bad. Ideas? I've tried brake fluid and brake cleaner... I'll just keep throwing things at it until it works, unless I get other suggestions. Thanks!
