A retouching/re-touch varnish isn't permanent, and will never dry - it gradually evaporates (basically). Someone who didn't know this wrapped his paintings in newspaper to send them to an exhibition - he got newsprint stuck all over them, which then had to be picked off, with great difficulty and tweezers....
But applying permanent varnish too soon, ie before at least six months have elapsed, and longer if the paint is at all thick (I have no knowledge of either Krylon or Kamar varnish - a link would be interesting) runs the strong risk of destruction of the paint film by cracking.
ปรกติคนไม่ชอบ vanishing เพราะมันเป็นตัวทำให้ภาพเหลืองเวลาเก็บนานๆ. และภาพเปลี่ยน .
