Tried a load of products over the years, now I'm 90% chemical guys.
I use their gloss detailer, jetseal 109 is the best sealant I've ever seen, glassworks, bug and tar remover, xxx wax, black wax, cherry and lemon/lime air freshened. All are great.
Tend to use Meg's clay as halfords stock it, bilberry wheel cleaner and it's good vfm, and menzerna polish with my DA as it came with it.
