Is it possible to brush paint aluminum on plastic models? I don't have an airbrush, etc. Can I simply brush? If so, how can I optimize the surface to eliminate obvious brush marks?

Thanks,

Dave,
about the only way I can think of to do this would be to tape off different sections or panels and do one part at a time. Trying to do a whole wing or fuselage at one time is gonna be tough brush painting.
One other tip would be to lay down a good coat of primer first. The paint brush wont do as much slipping and sliding on primer as it will on slick plastic.

I'd recommend using Humbrol Metal-Coat enamels. Brushes the best, and dries hard as nails. They also have/had a polished and a matt aluminum.

I know they can be like using a fire hose to water a pot plant, but what about trying a rattle can ?

Try using a brush, with short(ened) bristles, and stipple the paint, with a short, almost stabbing, motion. This worked for me, pre-airbrush days. I also found it useful not to take a brushload straight out of the tin, but to use a flat piece of metal, for stirring, then lodge it, at an angle, across the tin, with one end under the tin's rim. This allowed some of the liquid to drain back, leaving more solid colour for my brush.

As already written a good mat undercoat is important. Then use the paint slightly thinned and use several layers. This helps eliminate the brush stroke marks.

Good luck

Thanks to all. If I make any progress, I'll try to post the pics.

BTW, what is a good primer to use?

A general automotive grey primer from a rattle can - i use Halfords over here, but any primer should do - maybe one of our American friends can suggest a brand.

Yes, I use a grey car primer as well. However, remember it must be a matt primer. Otherwise it will be more difficult to cover and avoid brush strokes.

Thank you all for your help. I pikced up a couple of rattle cans yesterday at the local hobby shop.

When I make some progress, I'll post the good, the bad and the ugly.

Now if my old eyes will just handle the 1/72 scale!!!
