Pretty new here so I don't know anything about building lures, but I know automotive paint. Auto Air Colors will work with all urethane clears. Water based candies are 100 times more forgiving then solvent based candies (House of Kolors). The problems that arise with solvent based candies are becuase these colors are essentially overly reduced to give the transparent affect. The more reducer makes makes the the paint more sensitive to film thickness, flash times between coats, temp and humdity. Reducers act as thinners and release from the paint while its flashing. This means to heavy a coat, to short of a flash time or the wrong reducer for the tempature will affect how the reducers release or become trapped and cannot release. These candies also being so thin are why you see alot striping or blotching on larger areas - as said before. Alot of this sensitivity is lessend in the water based candies because of non chemical reducers, but the same still apllies. What you are essentially doing is is putting a chemically drying D2T over a physically drying Auto Air Color. I am going to assume the D2T will bite much more agressively into into your basecoats than urethane clears. When it is cures will odviously create a vapor barrier. To make this work you need be sure the physically drying basecoat has completly evaporated its reducers before topcoating. If i remember correct Auto Air colors doesn't have a topcoat window so make sure your bases are beyond flashed before applying the D2T, maybe paint them in the evening and topcoat in the morning. I bet it will work.
