The downside of the matte acrylics available is a lack of pure colors. The downside of acrylics that are pure is an inconsistent finish ranging from matte to satin to gloss depending on color and brand. In the past ive used Tamiya additive or Reapers anti shine additive. Never cared for tha Tamiya but Reaper worked okay. I purchased Badger Air’s Minitaire paint line Flatitive. Big bottle that mattes better than the Reaper. You only need a very small amount say a brush full added to four brush fulls of paint. Anything more will give chalky finishes. The advantage is a little goes a long way and the eye dropper built in gives a lot of control. Its very opaque and liquid. I think my days with Dullcoat are over.

So you mix whilst painting vs airbrushing after completion? Does drying time, brush handling, wet palette get affected?

That is what like about it. Does not influence the poperties of the paint. You just have to be careful of how much is added. Like matt medium a little goes a long way. Wet palettes I don’t usually work with or well palettes. I like to use glass or blank cd’s. Paints like P3 and tube color like Schminke, Liquitex and the like stay wet longer than hobby paints. A pain to keep mixing cooors but it works for me.

I currently use oils, but P3 was my preference..but i have to mail order everything and in winter all the acrylics arrived frozen and didn’t reconstitute. I did find they mixed well..

I use oils also and that is what I like about the P3 line. The extender in the paint and overall feel is like working in oils. Is there not a dealer in Canada?

There is ..but unfortunately winter and acrylics don’t mix...deliveries get frozen.
