I've had one (frame) cerakoted through CGW and, as Earl noted, that one was sent out. Since they moved and have some new 'toys', some specific aspects of 'custom finishing' may be done in house now...not sure. Give 'em a call or shoot 'em an email.....they're more than happy to talk with you about it. If a certain finishing did not hold up well, I really don't think they'd use it....or, if you insisted, they'd tell you straight up what to expect (if they'd even agree to go ahead with it).
