I use their stuff all the time. I perfer EX (carnauba) over the EX-P (Synthetic). EX gives a little deeper shine, but it is probably not as durable as EX.
I apply it thin with a soft buffing pad on my PC.
Bold N' Bright is the tire dressing I use most. It's thin stuff. I spray it on a Eagle One Tire Swipe and wipe it on the tires. Not too greasy.
Spray N Wipe is a great QD for a dusty car. It also seems to have a little cleaning power, which is good for helping you wipe off some bugs on the front of your car.
Spray N Gloss is a great QD. Easy to wipe on and off. Not oily, and won't leave streaks that need to be buffed off. Pretty slick. Not much durability, but I don't apply QDs for protection. I use QDs for making the paint look good when it's not dirty enough to require a full wash. I usually dilute a bottle of Spray and Gloss 1:1 with water and it still works good.

I like all the PoorBoys SSR polishes.

I use SSR 2.5 the least. I use SSR3 and SSR1 the most.
Bug Squash

Works great in a small bucket of wash water. Presoak the bugs with it and scrub a little.
