I have not used automotive clear over the Tamiya acrylic but I have used it over the Humbrol flat enamel and Testors ModelMaster enamels with no problem. Light mist coats at first. In the following photo, the red, white, and blue on the tail are Testors gloss enamels and the black on the wingtip tanks is Testors flat black enamel. The dark gray inside surface of the flaps is Humbrol flat enamel. I also have a very large F-86 that is painted almost entirely with Testors ModelMaster enamel. The clearcoat on the T-33 is DuPont Nason with a 2 to 1 mix of clearcoat and flattener. The clearcoat used on the F-86 is PPG "Flexed-N-Flat" clear:

Status: offline 		I don't know if this helps but I have used Lustercote without any problems at all over the Tamiya. I have heard and someone may want to chime in to confirm if Lustercote has the same properties as automotive clear.

Status: offline 		I have done exactly what you are asking. I painted a whiplash with the Tamiya paints and cleared it with Dupont Chroma-Clear. The only problem is, that if you get ever the tiniest hole in the clear, from a scratch, drilled hole, etc, and glow fuel, raw or burnt, hit the hole, poof, the tamiya paint wrinkles instantly. The bubbles under the clear and will acutally run under the clear attacking the paint. It is not pretty when that happens. If you are using Glow, I would find another paint.

Status: offline 		Exactly like minwax. I cannot give you exact drying times. Depends too much on how thick you put it on, what the weather is like, etc.,etc.,etc. Several hours will probably be plenty.

Steve: Beautiful bird. Since REAL airplanes have round engines and two wings, that one satisfys at least one of the criteria, and so is acceptable. The solvent based polyeurathanes where slightly yellow out of the can and turned more so with age, but the water based ones are water clear, and stay that way.
