My go to for detailing stuff is cleanyourcar or polishedbliss, and occasionally theultimatefinish.
I totally agree with you about wax. I love carnauba wax, and also like hybrid waxes with a high carnauba content. Regardless of whatever else goes on the paintwork - sealant, glaze etc, it's always topped off wax which is then layered over time. Carnauba wax offers a depth and gloss that you just don't quite get with anything else.
Like you, snow foam is part of my normal wash regime and would never miss it out. It's a bit of a divisive subject though, some don't think it offers any real benefit, but I disagree.
Waxing every week - that's devotion for you!
