Uschi 4009 Metal Polishing Powder - Steel Type 25ml

Opportunities in application

Cotton bud / Cotton cloth
The application in a polishing manner is what the product is basically designed for. As a basecoat I recommend flat, semi-gloss or gloss black colors, depending on the subject you work at. Allow the material to link into something. If you have a superpolished black basecoat you may find out that the pigments not really adhere when you try to polish them in. The solution in this case would be a semi-flat basecoat. The shine will come when you polish the powders in. Consider application by airbrush as well.
Another interesting point in even surfaces is, that the best time for pigment application is when the color is touch-dry and stable, but not fully cured.
For Gunze Acrylics (Or Tamiya) this is within like 1,5 - 6+hours.


Application by airbrush
The application by airbrush has the advantage of creating a chemical bonding to the surface. Use the same thinner that you used to thin the basecoat color. Consider colors like blue, red, yellow and even white as a color for the basecoat too. Use your trusty workhorse Airbrush for the job to avoid clogging your fine art airbrush. I wouldnt recommend to use a 0,15mm Nozzle set. It works, but maybe you will have to move the needle a bit back and forward sometimes to get it going again. Use a bigger one instead.

Flat panels and complex shaped objects
Complex:
When the object is rather complex, like an engine for example, I would recommend to use a black (or very, very dark grey) flat basecoat. This way we make sure that we have a nice depth because we have dark corners. I would recommend to shoot the pigments through an airbrush first, polish it up and apply further glossy spots using a cotton bud after, creating polished highlight thats way.

Flat panels:
Here we have the best opportunity to apply variation by altering the basecoat colors. As said above, consider colors like blue, red, yellow and even white in order to achieve variation. Please always do run a tesbed before you work on the real model. Make yourself familiar with product.
