I hate to do this even more but:
regular wax coating, which is not durable, lacks the ability to build layers because the solvent grit of the second coat destroys the first coat. With FINISH FIRST the more coats you apply, the deeper the gloss and the greater the protection
If a wax cleans, it cannot be layered!!! The cleaning will dissolve that other coat you just put on!!!! Good lord they need to reword this.
With a cleaner wax, you always end up with 1 coat of wax.
