If it definitely an inlay, then sand it, make sure not to sand through the inlay, then mask it off when you paint unmasking it for the clear coats.
You can mask it with any painters tape and a razor blade. Put the tape on, smooth it out with a credit card or something similar and then use an exact knife or razor blade to cut away the logo. I've been favoring green tape over blue tape these days but they'll all work.
If you screw it up, then have a look on the bestdecals website, they'll be able to make you another hamer logo including the USA lettering, then apply that before the last clear coats
