OK folks I've known about Dawn and other topical automotive "wax strippers" for a long time, but I 've never used any of them...Ever. To be honest I've never thought about stripping wax before I re-waxed and that may be a mistake. I have always had questions; about product compatibility, the protective duration of any given product, and other such questions. I know many people have their own specific product that they use and I understand that. What I would like some feedback on is; How often do you use a wax stripper? Why?(what is gained) and what are your thoughts about changing up your selection of wax without stripping? Is there any evidence to indicate that using different brands of waxes on top of each other will effect the finished outcome? I would also be interested in your impressions on the difference between standard Carnauba based waxes vs. the newer "synthetic" based waxes? Lastly, what is your personal rule of thumb for the frequency of re-waxing and what "tells" do you use to make that judgment?
