ChemicalGuys.com is the spot for me to find great products, great service and fair pricing. Try their 50/50 concourse paste and Jet Fuel protector. You will not be disappointed. Orders usually ship next day..
another vote for chemical guys. all of their products I have tried, I really like. if you wash your car a lot, then go for the gallon size jugs. it's really economical compared to the smaller sizes.
I cant comment on the concourse but can confirm the jetseal 109 is a really good polish/sealant. I also like their diablo wheel cleaner (I have not had to scrub a wheel since using it). and for wash soap, I have one of their foam lances so I use their foam (citrus wash and gloss) and they really give a good suds with either the pressure washer/lance or the bucket method.
