I sure dont know about "best" but have gotten really nice results with a good cleaning, then a couple coats of silicone based car wax buffed clean, followed with 2 coats of armorall's tire gel also wiped in and excess cleaned. the wax starts the making of a slick surface, and the armorall gel after makes it even slicker than that.
it might be a rookie maneuver, easy grab from the garage or autozone, or maybe its really good! (?)
the tire gel after trying to wipe it away near completely still leaves a very thin oily slippery on surfaces that reduces friction a LOT. did the whole job a couple months ago, gave it a fresh re-wipe of the gel stuff just last week.

not really personal here, but a pf, and mylar'd pf really isnt anything to do with fine furniture at all.
when was the last time you saw a nice wood coffeetable getting a 1-1/6" chrome steel ball bounced across it for hours, days, months, and years? I'm not saying carnuba is bad but theres reasons why about modern car waxes:
its fast, thin, slick, puts up with abuse of outdoor environment to protect paint, says a lot of good things to me.
this is about a machine, machines perform actions, actions produce wear etc.

the armorall tire gel, I kinda look at it this way: there arent many car engines that youd adjust valve rockers with zero clearance, they need a film of oil to cushion and lubricate metal to metal contact and impact. the very thin film left behind by the tire gel behaving similarly. same as wax getting into the pores of the paint and putting a film layer over the surface, the gel stuff seems to do the same thing with the wax on an even smaller scale so the surface gets even slipperier. the wax protecting the pf, the gel stuff protecting and lubricating the wax, I'd consider a win-win. "glass wax" is relatively new and also a synthetic, its pretty impressive stuff too really.

same reason I wax the ball itself, brand new shiny polished chrome has micro-pores that the wax will help fill.
seriously, give it a try Bob. a very small amount (dime size spot, if the pf is really smooth it'll be plenty) of armorall's tire gel on a cloth and spread it in over the whole main pf area, followed by a clean soft cloth to buff and pick up any-all excess.. only way to know is to play it. 2-3 coats of wax was good, the gel on top of that made things even faster for having less friction, it might really surprise you, it sure surprised me, wouldnt tell it if I didnt see to believe it.
