That’s what makes this coating different and why you should be charging a surplus for its application. It’s TOTALLY different than a sealant or wax. It requires a clean surface to promote the best possible adhesion, therefore creating the best possible results. Not only does the surface need to be clean, bare AND dry, it should also be corrected to the best possible level. That way you’re applying this true sacrificial barrier to the absolute best possible substrate. If not, you’re locking in those flaws thus creating an inferior product. And if you’re polishing, that means the polishing solvents and oils as well as the dust/debris must also be stripped from the surface prior to application. That requires an APC, strong chemical wash or alcohol decontamination (or combination of them which I do). Also keeping in mind that when doing an alcohol wipe down, you’re not spreading the contaminants to other clean areas of the surface. This means constantly being aware of using a clean portion of the MF and constantly swapping out for a fresh one as needed. Again, all this takes time AND skill to be able to perform the best possible treatment. Rarely, if ever, do I (or anyone I know) go to that level to prep a surface for wax or sealant.
And you’re entitled to your *opinion*, but so is everyone else. And at this point, everyone feels it takes more than and hour and should be a premium priced service. So, I’ll stand by my statement too.
