So I'm new to sealant, I've never used it before, but want to try on my new car. I have been washing and waxing my car on a regular basis since I've had it. So before I try to apply the sealant, wash, decontamination, then sealant? Or am I missing a step and need to do something to remove any old wax? Or will the Iron X take care of that? I didn't really want to polish my car unless I had to since I don't have a buffer and it would all be by hand, but if that's what it takes, it'll get done.
