Ditto. The MTK will air dry as the solvent evaporates but since we are missing the catalyst there won't be any cross linking (curing). Chemically the finish will be very unstable and the mildest of solvents will wipe it right off the plane. I would let it come to an air dried stage and then SAND it off and re-apply. Yes, I said solvent will take it off but you'll most likely destroy the primer ( depending on what you have used ) in the process. Hopefully the portion you have painted is small. Don't worry, you can fix it and I bet you won't make that mistake again.

Best of luck,
