I used to be a strictly Mothers guy. I had all three complete lines, the Cali Gold, SynWax, and Reflections lines. Each had their hit and miss products I found. Then after trying some stuff on AG, I dropped a lot of their stuff (still like their glass cleaner, and protectant, and old product they don't make called Trigger Wash, and their clay).
Now I'm a mix of everything, but if I had to pick, it'd be Wolfgang for the time being, their TSR kit, is basically relabeled Menzerna in a way. And the DGPS and Fuzion are awesome, also love the tire gel. Haven't tried the free clay yet though or the paintwork lotion.
I do love me some Menzerna for the polishes though, and Klasse AIO, and some of the Surf City stuff. The car wash is nice. ONR is what changed it for me though, that sent me on the path. Now I just got the VIP of the DP stuff, let's see how it stacks up!
