Sealing hot pipe to HX40

I finally have my 40/3B twins installed. When I close my exhaust brake and check for leaks I am getting a leak between the hot pipe and where it bolts onto the 40 with a copper gasket. Not a gushing leak but it's still there and I'm not sure how much effect it will have. I guess for those surfaces to seal air tight with the copper gasket they'll have to be flat within a few thou. which isn't the case.

Anyone ever used a thin coat of hi temp sealer on the gasket face to get a nice tight seal? Maybe some hi-temp RTV or ? I'm thinking about pulling the gasket, giving it a thin coat, put it together and snug the bolts, leave it over night and crank the bolts up the next day.
