You can polish it - but Activator+ has been known to react very erratically when glossy, or very strongly in general to surface changes. With polish, it is love or hate, and very condition-specific.
Another option I can think of is to try a fine base grit and then apply Rough Buff - this will also give more length, but I am not sure about the overall reaction because RB is very abrasive/coarse. I found that this does not work well, kills the reaction - but it might be the solution you are looking for. A 1.000 grit base or finer should do.
Another thing that comes to my mind is to try a very fine compound finish, e. g. the 3M "Finesse It" Trizact compound. It will, on a fine base grit, yield a glossy surface without polish. I made quite good experience with it on PK18, the ball glides well through the heads as long as there is some oil, but the back end read is quite consistent - even though the ball will have a little less length than a truly polished one.
Good luck, though.
