Question
I have a 2k poly top I would like to polish. With the Festool, do I start at 320 grit and go up to 1200 grit and do I use 3M Finess? Are there any videos start to finish?

From contributor F:
Get an assortment of Abralon pads. Depending on the sheen you want, start with the 500 grit for a low satin sheen or progress up to the 2000 grit if you want a high gloss sheen. I do this with my Festool 6" sander set at the medium setting. When using these pads, it is not necessary to drown the finish with a lot of water. I just use a spray bottle to mist on the water. This cuts down on water flying all over the place.
The process involves removing whatever imperfections the gun left, then removing all the damage your abrasive left. I find it best no matter what gloss you are after to wet sand to 2000, then either compound and glazing compound to a high gloss or scuff it down to a satin. Drop a little dish soap into your spray bottle; it will help with lubrication. If it is an outside bar, you should use either 3M Fenessit or Meguiars 9 to glaze in all of the sanding scratches that are left from your sanding process. If not, you have essentially doubled the surface area of your film and will hasten the degradation of your coating. Meguiars makes a very good carnauba yellow wax to finish off the top.
It looks fantastic at most angles and in the sun, but there is random haze on it. Can I get some 1200 and 1500 and 2000 grit to continue to remove the haze? Will the wax I put on mess this process up now?
The auto supply has some 3M paper but recommends RPM of 1500-2000 rpm. The 150 FEQ Festool has a rotary rating of 660rpm and an eccentric motion of 3300-6800rpm. Can I use it in the eccentric mode to achieve my required speed or does it have to be on rotary? I'm going to get some platin papers for Festool if I didn't screw it up already. Thanks for the advice so far - it was huge.
