I have been reading just about every article I can on AG so I can get deeper into detailing my own car and I was wondering if it is absolutely necessary to clay and/or polish the paint before putting any type of protective wax/sealant on? I am still building my arsenal and plan on doing a full decon in the near future, but until then what product(s) should I be using to protect the paint? I have some WG Deep Gloss Srpitz Sealant, but noticed it says it is intended to be used on an oxidation free surface, and further goes on to recommend polishing and claying prior to use. I am not expecting incredible results without first claying/polishing the paint, but just want to make sure I am protecting it until I can do a more thorough detail. Thanks in advance!
