The fellow that's doing long term car wax and ceramic sealer tests has published his latest 5 month review. My personal favorite traditional car waxes (Collinite) are still hanging in there but showing slight signs of weakening. Not bad for a 5 month test especially since they are competing with SiO2 Ceramic sealants.
