UK Kandy should be cleared immediately. You should apply your first coat of UC or UFC clear as if it were your next coat of Kandy. If you let the Kandy become hand slick you must wait 12 hrs. then scuff with a red scuff pad before applying more Kandy or a clear coat. Failure to do this will result in wrinkling of the Kandy. If you want to do art work over your UK Kandy, first clear the Kandy, let it dry, sand with 600 to 800 grit wet paper and do your art work over the dry clear. Do not apply SG100 over UK Kandys!
