Lots of great advice from Jungle650!
A liquid detailer, or gloss enhancer, is always a good idea on PPF because it's so much easier & faster to work with and MOST importantly, won't damage the film, or leave a dirty wax build-up at the edges - which can be a real PITA to remove!!
I used to enjoy the whole polishing/waxing process but being old and decrepit have moved on to liquid ceramics/sealants. My 991 has PPF with Gtechniq Ceramic but I use Gtechniq Liquid Crystal as a renewable 'top-coat' and you could do the same - it gives a nice shine, can be layered for extra depth and lasts about 6 months, so I only need to clean (see below) and re-apply this final layer twice a year, then use Gtechniq QD, at the end of each wash - to dry off (after a 0ppm rinse & blower) exactly as Jungle described.
Nowadays, there are a range of specialist cleaners for PPF, from the major car-care brands but whilst modern PPF is more durable than the original stuff, you should avoid anything that contains Petroleum Distillate, which can damage the PPF and cause it to yellow!!
My own cleaning regime, once or twice a year before applying the sealant, is a full snow-foam, two bucket wash, 0ppm rinse and blower dry (out of the sun) followed by:
1) Clay Bar Decontamination: Use a Chemical Guys clay bar 'Light' (very fine) OR Sonus Ultrafine and QD spray to lube sections of each panel - making sure to fold the clay inwards regularly, or use a new piece and taking great care to avoid the PPF edges (or you'll end up with another nuisance job) - this will remove any bonded contaminants and make the surface slick, smooth and ready for the next step.
NB: People think you can't clay PPF, you can but just need to use a fine/ultra-fine bar, plenty of lube and avoid those exposed edges.
2) Use one of the dedicated PPF cleaners - either the Xpel one mentioned in T8's link or from Bilt Hamber, Gyeon etc to clean one panel at a time, before spritzing with distilled water and drying off.
3) Apply Gtechniq Liquid Crystal C2V3 to a clean MF and apply to part of a panel, before wiping off the excess with a clean MF and over-laying each pass slightly as you go. After a few minutes, finish each panel with a final buff, using another clean MF, to enhance the gloss before moving on.
Unless you feel particularly wedded to your existing wax regime, you could just use Liquid Crystal on the whole car but I appreciate waxing can become a religion (I remember), so whatever you feel comfortable with. Either way enjoy.
