This is first time using carpro ceramic I applied 2 coats of Uk 3.0 let it set 24 hrs then applied Sic and had issues with the flashing and buffing off the Sic. There were blotchy high spots all over. I applied a second coat of Sic and buffed off while it was slightly wet still to remove the high spots which worked. I just skeptical now in doing this did I compromise the original Uk 3.0 I put on. I still have enough Uk and Sic to do a coat of each. Is it ok to apply Uk3.0 over Sic?
