I'm finding Folk Art Metallic paint difficult.

I've used folk art paints in my airbrush, but not the metallic paints.  They may contain particles that help with the metallic sheen, like the old square-bottle testor paints.  After thinning, you may need to strain them through a fine metal mesh to get rid of any lumps before you load it into the airbrush.  Of course, this may remove the metallic effects.

 I also find there is a place for craft store acrylics.  House brands for some of the stores have an incredible number of colors right across the spectrum  If you are doing something different, for which there is no hobby paint available, you may need to mix some  paint.  It is a lot easier to do the mixing when a wide spectrum of colors are available than doing it only from four or five primary colors.  I use Michaels house brand.  I mix it with isopropyl.  Once I found the right mixture ratio, it airbrushes fine.

Wow, would never have thought of using alcohol for these types of paint. What advantage does it give over using water?

From what I've been reading up on that particular brand, it appears they're basically an arts and crafts paint. No one here uses such a brand at all...

 

 

 

I must respectfully disagree with that statement.  There are many modelers who use craft store acrylics.  If you do a search of the forum on "Americana", "Apple Barrel", and "Folk Art", I expect you'll find posts describing their use.

The advantages of the craft store acrylics are that they can be thinned with water, have no fumes, can be applied by hand or airbrushed, and that they are cheap for the per-unit price.  I use them for weathering, and I've started using them alongside my Andrea and Vallejo acrylics, to paint figures.

Now, there is a disadvantage, and that is that they are craft paints, as you noted.  Their pigments are not ground as finely as those in Andrea or Vallejo paints, or other paints made specifically for scale modelers.  I found that out myself, when I used a craft store acrylic for the underside color on an airplane.  The paint went on well, but the finish was rough, because of the coarser pigments.  However, I've had discussions with other modelers who have said that they didn't notice that effect.  I haven't tried to work around it yet, but I suspect that I might be able to mix a batch and let it settle a little before applying it.

Hello!

While that mightr be counter-intuitive, some metallic paints, like the Alclad 2, require black primer to show some effect - sprayed on light surface they only give you slight glitter while on black surface the same amount of paint gives you a defined colour - so maybe this would be worth a try here. Hope it helps and have a nice day

PS. Humbrol used to be a craft store paint before modellers started using it

Yes, you’re right. I should have written 1.0 bar and 2.5 bar. Its working out fine now. The Testors metallic is just beautiful. Finally, after banging my head against the wall I’m understanding the pressure/viscosity balance. I’m  suddenly enjoying this! Thanks to all for the advice. John

You mention 1.0 and 2.5 PSI. Those pressures are incredibly low and it's doubtful you'd get any sort of paint flow. Do you mean 1.0 and 2.5 bar, perhaps? (14.5 and 36.25 PSI respectively)

Thanks for the advice. I use acrylic paint so fumes are not an issue. I finally got Testors Acrylic metallic to work. I wasn’t thinning it enough and the 1.0 psi is fine.  The paint flows smoothly and consistently now. I let it dry and then polish with a dry towel. It looks great. Best John

A primer would definitely help. I have seen some folks use craft paint successfully, but I haven't seen the metallics used. Are you spraying other acrylic colors with no issues? Is the metallic mixing well in the cup without clumping? I wonder if the metallic particles are too thick for the brush. I spray Testors enamels with their airbrush thinner myself and can recommend it, just be mindful of the fumes.

From what I've been reading up on that particular brand, it appears they're basically an arts and crafts paint. No one here uses such a brand at all. Stick with basic hobby related paimnt brands instead, Use the paint brand's own thinner line before attempting to try cheap alternatives until you get a better understanding in airbrushing.

Yes, a coat of primer is recommended before top coat. my go-to primer is Rustoleum brand dry/wet sandable primer in rattle can. I use either grey, white of even black depending on the subject.
