What's a good durable, hi heat, scratch resistant, easy to bond, matte black paint to use on a stainless steel barrel?

I have a reasonably new, very clean 7 rem mag barrel in SS and all my actions / rifles are matte black or blued. I'm just breaking into the wonderful world of the 7mm round by loading for & shooting a 7mm-08. When I get bored or tired or both from that one, I'll probably swap it for the rem mag but, not while it has a ss finish.

ANyone got any suggestions? I'd like to use a paint that'll bond well & not scratch or chip if I look at it the wrong way.

Talk to me.....
