Build model, paint all the main colors on al let the paint cure. Before you remove masking, spray, or brush on a coat of future over the whole model. Put all you decals on, then put another coat of future on, especially over the decals. Let this all cure for a a day or two, then you can spray dullcoat on if you want. Alot of guys will do weathering before dullcoating also.
The main reson for the future coats is to give the decals a nice even surface to sit on when using flat paints, it's the best way to avoid silvering of the decals and can make them look painted on by hiding the decal carrier film. Plus a flat painted model with glossy decals funny.
Swing by the local hobby shop and pick up a couple copies of modelling magazines like SCALE MODELLER, every issue is full of hints and tips, even some of the car tips can be addapted for aircraft models.
