I agree, don't give-up so quickly.
I can't comment on your product choices (never used them) but I had great luck with SSR2.5, VM, and EX-P first time out & now I'm always in search of better .... in search of more shine, more depth, more lower balances in my savings account.
Give the Poorboy's products a try, they're designed to suit the needs of the weekend hobbiest looking for a better shine as well as the detailing profesional.
Call or email Steve (Poorboy), he'll offer good advice.
