OP, great and informative post. I'm still a little confused though (it doesn't take much!
I just got done a couple days ago waxing my car with some type of Meguire's liquid wax that you pour onto a pad, rub in, let dry to haze, buff off. Not sure exactly which one since I'm not home to look at the bottle right now.
I also have a bottle of some higher-end (again, not home to look so don't remember the name/manufacturer) sealant that was given to me as part of a car care gift package.
My question, even after reading your post, is would applying the sealant now be kind of a waste of time since I just waxed it and it sounds
like to me that they do essentially the same job?
