Will a clear coat solve my problem?

[eric2448]

A few months ago I asked a question about paint not drying correctly. I'm using Floquil Silver Enamel through a dual action airbrush. The paint has been on the cars for months and I was just able to strip them clean with 91% alcohol. I normally have to use Super Clean to get the enamels off but not with these cars. When I respray these cars, if the paint continues to not dry properly would applying a good clear coat help? If the base coats don't dry properly will it cause the top clear cot to not dry either?
