grats bro. so the 15 do come with white pads while 21 is green/yellow

please consider searching this thread for questions that have already been answered if you're serious in maintaining your car.

there are plenty of Q&A done for watermark removals.

then there are also many repeated guidance on proper detailing steps and maintaining steps.
example:
detailing
wash > clay > wash again (my preference in getting rid of clay lube/products/me just being OCD etc) > dry > compound (if needed) > polish > glaze or IPA wipedowns (if needed) > coating (if preferred) > wax/sealant

weekly regular maintenance:
wash > dry > maintenance wax/topper such as meguiar's ultimate quik wax or sonax brilliant detailer or duragloss aquawax (or DG951 http://estore.duragloss.com.my/webapp/wcs/...isplayErrorView )

for proper washing, do use the 2 bucket (or 3 if you OCD) system, with grit guards
search in this thread/google it if you're not sure. got youtube guide too.

get plush microfiber cloths and/or drying towels if you don't have any proper ones.

layman in detailing/examples: will rage even seeing 1 dust on car, see microfiber cloth dirty also will flip table.

generally what i posted in illustration form

has the car been through accident? because seems like it's repainted and putty= the "clay"/filling (typically red/pink ish) after knocking of dents/body repair, then primer > base coat > clear coat.
