Has anyone tried using Klasse's Sealant Glaze over Meguiar's NXT? I was just wondering if this could help the NXT last longer and maybe add some gloss.

 

If your looking for protection that will last a long time than just a wax, what I usually do is put a coat of sealant (i.e. Meguiars #21 , or Klasse AIO, or Klasse Sealant Glaze) followed by a coat or two of NXT. That way, whent he NXT looses it affect, there is still the synthetic sealant.
