Brush On Acrylic Paint

[massplastic]

Wondering if anyone has tried brushing on paint instead of spraying. I've experimented on some old parts and find that with a good brush it will go on pretty smooth. Also, if I decide to spray acrylic through an airbrush, is there anything that should be done different with preparation (sanding, primer, etc) from regular enamels? Thanks

I have had pretty good luck brush painted MM Acrylics when they are fresh. Virtually no brush marks in the finish - at least on small parts.

Are you referring to painting glossy bodies, or to small parts or interiors/chassis/other areas that don't require a high-gloss finish?

If the former, well, it can be done, but I think it takes an expert, the right paint, and some luck. For chassis/interiors/etc you can absolutely brush paint acrylics. I have a slew of airplanes painted this way. Some rules of thumb: a primer coat REALLY helps (spray your favorite, though I like to brush on thinned artist's gesso), don't put so much paint on the brush, and build up the color with thin coats.

I like Polly Scale and Testors Model Master; Tamiya doesn't seem to work quite as well for me. My favorite, though, is Vallejo Model Color. It's hard to find and requires a special technique (thin with water 50:50 and mix well before brushing), but leaves a gorgeous brushstroke-free finish.

I should add that Future floor finish will level out to give a great gloss when brushed on. I wonder if a few drops of strongly pigmented paint (like Vallejo) could be added to some Future and brushed onto a car body to give a good result???
