The flattest finish of them all?

One other way to get a flat finnish is to mix dullcoat or flat into your base color. As usual, test on scrap.

Also, I do not know what you are painting but half the armor out there is not "dead flat" anyway.

Hi Don, that's exactly how I do it but some times I see a mild sheen not up to my taste. I've seen works from others with dead flat finishes and I wonder how. I just painted a Tamiya M1A2 ABRAMS with Acryl 33531 and love the flat finish of the paint without sealing my decals.

Have a nice day neighbor, I'm a walking distance from the MN Zoo.

How you apply Dullcoat has a bearing on how flat it will end up. If you put a wet, thick coat on, it will dry as more of a semi-gloss.  You need to put on a dry coat, or several dry coats.  From a greater distance and quick thin coats.

Depending on where you are in the world, if you can get it, Gunze's Acrylic clear flat (H-20) is hard to beat. Absolutely dead flat. In a pinch ir can be airbrushed straight out of the bottle, but it works better when thinned.

Future with Tamiya Flat Base. It can be mixed to be anything from semi-gloss to dead flat.

Actually the Flat Base out of the jar is the flattest, but it's also opaque white.

The only flatter finish that can be had is to use this;

Bgrigg - Interesting. I thought Tamiya and Future didn't play nice together. Guess it might be different with their bases?

Could you happen to recommend a mixing ratio to use as a starting point? I just so happen to have both items sitting around...

This is from Matt Swan's excellent article on Future:

Future does produce a glossy finish so many modelers will introduce a flattening material or only use it as a pre-decal sealer. If you wish to use flattened Future as a final coat here are a couple of suggested ratios of Tamiya flat base for different effects:
      1 part flat base to 3 parts Future = very flat
      1 part flat base to 10 parts Future = flat
      1 part flat base to 15 parts Future = satin
      If you get too much of anybody's flat base on the surface of your model you run the risk of making it all go white. No thinning is required just make sure it is well mixed.

Tamiya plays nicely with Future. Future doesn't play well with any of the decal solvents, at least not for me.

Thanks for the pointers guys. I've heard somewhere that Acryl flat clear (4636) thinned with Windex gives good results. How good is it? I have both available, Gloss and Flat Acryl in 1 oz.

Polly Scale Flat works for me.

Curious to know this one myself. I tried switching to Polly flat on my Dauntless and was rewarded by white flecking. Not happy, so back to dullcote.

I'm tempted to try grabbing some Valspar/Krylon/Rustoleum flat varnish and giving it a go. Definitely on a test piece first, though.
