I use a lot of Adam's stuff but I also lurk this forum daily and soak up as much info as I can. It's good you finally bought the Menzerna polishes because for a few posts there it looked like you were "breaking your head" over which way to go. My suggestion is go ahead and try out the Menzerna stuff, no need to stress out over it.
I have the Adam's two step corrections system and really like them, especially the finishing polish which gives you a ton of working time (the old polishes didn't work for me) but I also have the Meg twins and the D300 and a few others. Not all vehicles paints are the same so it's good to have different ones on hand to accommodate different vehicles.
As for Dylan leaving, I was truly shocked. I really liked that guy, he was very active on the forums, very nice and really knows his stuff. First Chase and now Dylan.
