Hi, I'm a newbie here and in car detailing world. I'm a klasse AIO user recently. Everytime I wash my car, I use AIO to finish the job. Then, I read some threads about klasse sealant & glaze and many people like to use that. I'm also thinking of applying sealant&glaze soon. So my question is, on every car wash should I use AIO first then sealant&glaze after that? or should I just use sealant &glaze instead? If anybody could explain it to me, I'd really appreciate it. Thank you.
