Im getting a HK P7 PSP tommorow that needs a finish for cheap. I need a finish that has good thermal dissipation or heat transfer because the PSP model does not have the American P7's heat shield in the trigger guard.
If i can find a nice silverish finish that has good thermal properties(like jet hot coating or something one would use on engine headers) id be a damn happy camper.
Any suggestions?
Here's a pic of a P7:

(this is actually the P7M8 with the heat shield)
The wood grips cost about a $100, i'll lay out another $100 for night sights and another $150 for mag-na-porting. If i can end up getting the frame done for about $150 i should be able to get the P7 ive always wanted for about a $1000 total investment.
That would make me a very happy camper.
