Damn, that's a tough one. If could only work with only one of each:
Car wash: Autoint Decon (I can do a wash as well as paint cleaning in 3 steps)
Polish (abrasive):
Menzerna FPII (nothing else comes close, cept 85rd)
Polish(chemical): AIO (don't really know anything else)
Glaze: FK1 #303 Machine Glaze (good hiding, and longest lasting of all the
glazes I've used)
Sealant: Z2Pro (best looking sealant, IMO)
Wax: FK1 Pink Wax (Best looking wax, IMO, and hides very well)
QD: FK1 425 (does not strip off existing LSP, and leaves behind a very nice shine)
