that enamel is probably really old. did you try warming the can up?if you can get the ruby red to work for you ,testors also has a pearl gloss coat in the enamel so maybe try that if you want more sparkle . as for how long it take to dry could be a couple of days or a couple of weeks.in the future I recommend sticking to the hobby lacquers or tamiya paints. I know they're more expensive but it's worth it just for the dry time overnight as opposed to overweek.if you can't get it to smooth out try stripping it in super clean or use easy off(OUTSIDE WITH CAUTION). hope this helps good luck!
