Polishing Powders for Dirty Engines or High Gloss Chrome Finishes
It´s not AK Dark Steel, it´s not CMK Stardust, it´s not MIGproduction Phantasy Pigments, nor it´s something alike neither. This is a whole lotta different story.
So, what is it?
Uschi van der Rosten´s Metallic powders is a range of complementary metallizers, including the ability to replace existing metallizers on many occasions. It always depends on the situation. Machinery and Aircraft Exteriours are two entirely "different cups of tea" as they say. I would not rely on our powders only, having a full grown NMF project on my bench.
Natural Metal Finish (NMF) is one of the most challenging jobs in scale model building. The goal is to turn plastic into metal and make it look like real metal rather than a paint job. During the research for the release of our products, I followed exactly that goal: Make it look like real metal. I also had to keep Uschi´s key requirement in focus: Making things easy. Both has been accomplished and we now have another powerful tool to make convincing NMF easy as child stuff.
The key is in the mix. When we combine various effects, we achieve the complexity that forms a masterpiece. I would like to encourage you to combine our pigments with methods you are used to.
I would keep it with Gerald “Hawkeye” Voigt and one of his statements: "Modeling is a series of techniques, learn to master the techniques and you master the model."Uschi would like to add: "Load your toolbox of techniques with as many of tools as you can get. Pick the tool you like the most when facing a challenge. The more tools you have (techniques mastered) the easier it is to master the challenge."
Nuff philosophics now. Lets talk about solid metal.
Right to exist
I keep it short: The results are outstanding, handling is easy and the price-performance ratio is second to none. Thats it.
If we look on the details, we see that we have many triggers to play with, such as the basecoat´s gloss level, the color of the basecoat and the way to apply the product. (Polishing or by Airbrush)
Polishing pigments do change the look of "painted metal" a lot to the better on both, even surface or complex shapes. The product provides more variation and complexity in Finish.
In the following you will also see how we shoot the pigments through an airbrush. I used simple thinner with no color medium in it. Thats another interesting way to use the product.
All these additional options on rendering NMF are representing the product´s right to exist through the benefits it offers.
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
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.
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.
An article by Ian Henry
I found the pigment powder difficult to seal and handle as oils in fingerprints and stuff grazing the surface can mar and remove the coating over time. Every sealer I tried dulled the beautiful surface finish of the raw, buffed powder, until I found a great combo. Certainly not saying this is the best method, just what worked for me.
For both projects here I used essentially the same process, just with slightly different brands of materials.
Step 1: base coat black. I used a crappy hardware store rattle can black I had left over.
Step 2: 2k clear high gloss top coat. I used Spraymax 2k High Gloss from a can, 3-4 wet coats.
(It’s awesome stuff in a pinch but pretty pricey. 24hr pot life, no mess or mixing. Just pop the cap on the bottom, shake and spray!)
Step 3: Apply chroming powder. I used a cotton ball and dabbed it into the powder, then straight to the fully cured Clear (12-14hrs later) and buff it into the surface and be amazed!
Step 4: seal the chrome with a Liquitex High Gloss Varnish. I sprayed mine from an airbrush, but it can also be brushed on if necessary. Let dry according to instructions.
(Optional) Step 5: once it’s sealed you can then go over it again with another coating of chrome powder to brighten the dark chrome up a bit. I prefer double coated chrome to single. Just a bit brighter and deeper finish. Seal again with another coat of Liquitex.
Step 6: top coat with a few more 2k Clear coats for desired finish.
The end result is a super durable 2k chrome finish that’s rich, vibrant, and gorgeous. No one believes me that it’s paint and I feel like that’s the best indication you can get that it looks good. This is an amazing product that with the right materials is stupid simple to make an amazing finish. The small jar of powder has lasted me through tons of testing, a couple accidental spills, and several coats on finished projects and I still have over half the bottle left. One jar is all you need for dozens of models.
Thanks for your time and I hope this helps some people!
