Depending on the product, it might have constancy or bonding issues?
Part A by itself does not work well. Its is only half of a sealant. It needs to work with the chemicals in part B or Poxy for its best results. This may or may not be in the hybrid wax.
Normally, if someone was to layer a wax over a sealant, they would let it cure 24-48 hours before adding the wax. It may be a better to use Part A with Poxy, let it cure, then use a hybrid wax a day or 2 later.
