Thanks for the advice. The instructions for the specific spay cans I'm using says that I should wait two whole weeks for the colour to harden.. but doesn't say anything about using a clear coat. The clear coat also says it needs two weeks to fully dry. I'm assuming I don't need to wait the full drying time for the colour coat if I intend to use a clear coat. Is this correct?

My main concern is by leaving too much time between the colour coat and the clear coat that the clear won't bond properly or the finish will be affected....
