I recently got a CPO car and was about to do some paint correct before I applied CQuartz. After I washed with some dawn, clayed the car it is still beading water. That got me thinking if the previous owner had applied CQuartz or Opti-Coat already. Is there any way I can tell?
•Of the two Coatings you mention, CQuartz is
probably a "nano"-Coating (Opti-Coat on the other
hand is said to be a pre-polymer resin); yet both
are suppose to have a specifically defined hardness
and scratch resistance—said to be greater than that
of both Waxes and Sealants.
-{Note: The figure 9H, for some strange reason,
keeps cropping-up before my eyes right now.}
•One sure way to determine these
particular at tributes of Coatings:
-The ASTM test method D 3363 (Pencil Hardness Test)
is an effective method to test coatings for their
hardness and their scratch/wear resistance.
-This ASTM testing protocol uses pencils, of known
hardness values, that are to be moved over the
surface of test samples at a fixed angle and pressure.
-There are pencil hardness kits available at many
online outlets, if so interested.
