    I have recently finished a white metal Shay kit and wish to airbrush this model using Floquil paints.

    Since this is the first white metal kit i have painted i was wondering if there are any preparations proir to air brushing apart from washing the metal before painting.

    Should i use a primer or undercoat ?

    I will be air brushing the model using the colour Weathered Black.

    Cheers

    I think you should prime it first

    The primer does two things, it provides a better surface for the finish coat, and it provides an even, neutral color for the final coat to go over. This makes the finish coat more even, and helps it hold better.

    Just wondering here, but are painted metal models supposed to have the paint baked on in an oven?

    If so, be sure to get the right info - that means DO NOT ASK ME!! :D

    I'll bet that one of the local painting gurus could answer that.

    That not really a primer, its a color used for simulating the color of something like an unpainted steel bridge. Floquil primer is grey but if you don't have any automobile primer in a spray can will work just fine. Just use a light coat.

    one thing i do to white metal after washing in hot water is to soak it for a bit in a weak solution of vinagar to provide a slight tooth for primer

    Jim, That sounds like Real Good Tip!! (RGT) :D

    Do you see the shiny parts of the surface dull down a bit
    after etching for a while?? Sounds like it would help the
    primer/paint bond much better. Thanx!! :thumb:

    Depending on your final color, be careful of your primer color. If you have a light final color (white, yellow, lighter reds and oranges) a dark grey will bleed through. Of course if it's a shay to be painted black, any grey will do.

    Yes indeed, yellow and orange are especially transparent colors. They should always be primed with white. Floquil doesn't make a true primer in white but the white color should work fine. If you do want a true white metal primer try using one of the white primers for painting those metal role playing figures. GHQ is one brand that comes to mind.

    I've all but retired my Floquils paints in favor of the Polly Scale (not Polly S) paints. They stick to most anything like glue and have a much better finish to them and unless a primer is needed for the purpose of preventing bleed thru you really don't need to use a primer with them.

    Actually, I've found that the only good primer for gloss white and Gloss Yellow are the flats of the respective colors. Even flat white will bleed through gloss yellow, making it the most difficult color to paint.

    You could perhaps consider looking into the spray can primers availible for wargame type metal figurines found in some book stores and comic book shops that sell those games as well.

    The primer is specifically designed to go on in thin coats (1 or 2) and not lose the minute details on those figurines. It also comes in a white color.
