Apparantly not, its ment to be insane by itself, the World best that is....the polish is ment to be like a sealant too. Im tempted to use Worlds best polish on my car after machine polishing and then topping it off with Z8.
Z8 by itself, is great. My dads car hand been detailed for over a year and the paintwork was bare as could be, sprayed it down twice with Z8 and it beaded for about 2 months, i then took the time to do it properly and give it a coat of wax.
