I use 2000 grit from the auto section with water to remove lettering.
...
It comes off fairly quickly with that grit.
I bet! I should have been more clear - I don't want to remove all of it, just make it look worn. The 10000 does a good job, I just need to learn to make it look more random.
Swirling motion with varing pressure. Also, if you use something like solvaset or (carefully) use ELO, if you use a cloth and wipe over the lettering/logo with a downward motion, it makes it look like the logo's paint is running down. It will lighten the logo and give the run effect at the same time. Just don't wipe too hard or too long (no jokes....) or you'll take paint off.
