I put a bit of work into the golf paint the other day, I went through the following process all by hand and it made a big improvement to the finish:
Washed, 2 bucket, dried with microfibre
clayed
polished Autoglym super resin not very abrasive but also helps fill, using a polish applicator pad and straight up down motions
pre wax cleanser
waxed
this dramatically reduced the swirl marks without detailed inspection, cleared pretty much all the blemishes, and having used a good hard wax has left glass smooth paint and a high beading finish.
