Multi color jigs
I want to make some multi color jigs should I harden the base coat before I add the second color and third color.

Example - 1.
White base coat harden it, then over coat with Chartreuse, harden that then add a third color like Orange dusting and harden again?
That seems like a lot of oven time to me?

Example - 2.
White base coat harden it, then over coat with Chartreuse, then add a third color like Orange dusting then re bake?

Example - 3. White base coat then over coat with Chartreuse, then add a third color like Orange dusting then bake 1 time?

OR SOME OTHER WAY???

Thanks
