Capp325,
Rodger Kotanko explained to me that to do the inside of the frame they need to build a special jig to have electrodes touch inside of frame....small firearms community in Canada makes cost prohibitive. Also he prefers not to do internals to avoid dimensional changes.
The US hardchromers have more advanced techniques but once again, they can afford to due to huge gun market.
considering that Questar is no longer assisting one to export to US for refinishing, one can only use what's available here. They're also not doing 3rd party imports now so you can't even buy one in US, get chrome and import.
I asked Rodger to chrome my 2 P7M8's. At some point I'm going to go to US for target shooting and arrange ahead of time for Robar to strip the chrome and do NP3 hopefully while I'm there. For now the Chromed exterior will do. The stock bluing on P7's is really lousy.
