While I don't use any product line exclusively I did want to try some more Meguiars products. I'm looking to place an order at ADS soon. I currently have APC, Wheel Brightener, 80, 85, 16, 39, 40, NXT Glass Cleaner, & DACP. Are there any other products you've enjoyed using?
Other than the stuff on your list, Interior Detailer would be good. Oh and you might want to get a wash in bulk...I like GC, but I've heard some of their other washes are better.
I love wheel brightner! Definately my go to wheel cleaner for those tough jobs. I think my favorite tool from the meg's line up is the wheel bristle brush (the big yellow brush that reaches into the lining of the wheels) I use gold class wash but only for wheels, tires and wheel well duty.
Wheel Brightener, Quick Interior Detailer, OTC carpet cleaner, #34, Hyper Dressing and #80 about cover it for me. I'm a fan of all of the brushes as well.
Meg's Detailer Line APC and Wheel Brightener along with #34, #39, #40 and Gold Class shampoo are all staples of my detail business.
Aside from those I like the 80's series line (not the best polishes but far from the worst and they are all available in bulk sizes) and #16, #26, #20 and #21 are all very fine LSP's.
I use #80 like a mad man. I top it with either NXT Tech wax or Gold Glass. NXT is awesome for the price. Won't whiten your black trim either. Can't beat Wheel Brightner from the Detailer Line Up. I cut it 1:1 and it still takes care of Bimmers wheels. Make sure you don't inhale while you're spraying though. You'll be hacking for a week.
