Thanks a lot for taking the time to explain your layering conclusion so clearly and thoroughly.
As far as your test methods being insufficiently scientific go, I’m not sure I agree. At any rate, I now believe that layering more than two carnauba layers is unfruitful.
That was really in reference to the paraffin waxes used on surfboards. I believe the solvents that are used in carnaubas is primarily what prevents them from layering.
