Avon is a good piece from East Central, IN...
A closer alternative may be Highsmith in Greenfield. I THINK that he does Cerakoating work.
If you're going to be on the greater west side of Indy area, besides AllenM, there's Havlin's Firearms Finishing north of Brownsburg.
see my sig line.

I would caution against using Highsmith. I was warned but Unfortunately didn't listen.
I can recommend Allen. He did a rifle for me, and he's currently fixing some front end damage on my car.
I posted a message on his profile in this forum (don't have enough posts to send pm's yet), and he responded quickly with his phone number if I had any questions. I haven't had any work done yet, but I already like his professionalism. Definitely sounds like a stand-up guy!
Does AllenM do anything but coating? Is he a gunsmith as well?
