If I didn't have so much Liquitex matte sitting around, I'd go for some Krylon matte.  Heck, I probably will anyway.  Will continue watching :)

Yeah, so far it has been the best for me. Your milage may differ. Just be aware that too much can "go milky on you".

TEST NUMBER 6

Alclad II Klear Kote Flat
--------------------------------------------------

I'll come clean and say it, I avoid lacquers when I can, but I thought I would give Alclad II a go and see what would happen.
I do plan on using Alclad in the future for a couple figure kits (but probably not the flat clear).

From what I've read, Alclad needs to have a pretty smooth, uniform, and sometimes glossy, undercoat to spray well and Future can do that. So, for this test,
I sprayed the upper half of the test wedge with Future as uniformly as I could and then sprayed the lower half unevenly to see if it would have an effect. Some spots
I gave a lot of Future, and others only a couple lighter coats. If there was going to be some kind of incompatibility, I suspected this would be it ...

You have to shake the clear a lot to get it evenly mixed. When I tried to take the cap off ... CRACK ... it broke. Not sure what happened. There's a plastic
insert to keep the clear from getting to the threads, but I suspect some managed to get there during shipping. I don't know how common this problem is.
Fortunately, I had a another cap on hand that fit.

Alclad can be sprayed straight from the bottle and is cleaned up either with their airbrush thinner or lacquer thinner. Recommended pressure is 18-20 PSI
and very close distances, treating the airbrush more like a pencil than a sprayer.

This is what I got after three light coats.


As you can see, the upper part is pretty flat and uniform, while the lower is not. How well you spray the Future definitely seems to have an effect as I expected ...
So the lesson here, for me at least, is to be very mindful of your gloss coat. I suspect most of you who have sprayed Alclad before probably know this.

There is a rough spot to the right of one of the center hull plates you can see in the image. The Future here was particularly thin so it might be some kind
of interaction. Everywhere else, where the Future was thicker, seemed to be fine.

As for a comparison of the other flat clears. This is about as flat and smooth as the Krylon Matte. So if you're comfortable with Alclad, I think it should do the job ...
I personally don't plan on using it, but will if the need arises.

SUCCESS BUT BE MINDFUL OF YOUR GLOSS COAT.

1.) Krylon Matte Finish
2.) Model Master Acryl Flat
3.) Krylon UV-Resistant Clear (Matte)
4.) Alclad II Klear Kote (Flat)
5. - tie.) Testors Dullcote Spray Lacquer
5. - tie.) Valspar Project Perfect Clear Matte


I'll be off for a few days to help out my folks and to reorganize my workspace.
The last two tests will be witch's brews of Future+Tamiya Flat Base along with Liquitex Matte Varnish+Airbrush Medium.

TEST NUMBER 7

Future + Tamiya Flat Base (X-21)
--------------------------------------------------

I had a little time this morning to quickly try this witch's brew ...
I've seen this mixture mentioned on other threads and forums and it got my interest.

It's pretty cheap to make. I got the flat base for $2.39 at Scalehobbyist and a bottle of Future will last you a good while.

From Swanny's Models, the recommended mixes are:
       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

Any more base and you run the risk of the clear coat developing flakes or turning milky. So, for the sake of maximizing success, I decided
to mix:
       1 part flat base to 5 parts Future

knowing that it might not give me as "dead flat" of a finish as some of the other tests.

I used a graduated pipette to get the ratios right.


Spraying at 15 PSI a few inches from the surface, I put down 5 light coats as evenly as I could with a
couple minutes between each coat. There were a few shiny spots, but they leveled out and turned flat.

Here is the result...


I think I have a new favorite contender! This stuff is just as smooth as the Krylon Matte and UV Clear, is maybe
a tiny bit less flat than Kryon Matte and is more uniform than the MM Acryl Flat. I can easily see why a 1:3 mix
might be "too flat". Cleanup was easy, just some denatured alcohol and/or ammonia diluted to 5%. I used ammonia
last because Windex is known to gum up the Tamiya. Simple Green should also work.

I don't think it needs to be said but I'll say it, no signs of interaction with the Future gloss coat underneath.

With a bit of tweaking, this might just be my go-to for airbrushing. The fact that you can experiment with, and
then control the amount of gloss you get is a big plus IMO.

SUCCESS BUT SOME TWEAKING REQUIRED.

I need to spray some Future on the inside of the saucer for the last test, so it will be the weekend before I get to that.

TEST NUMBER 8

FINAL TEST:
Liquitex Matte Varnish + Liquitex Airbrush Medium
--------------------------------------------------

This is the last thing I'll be testing.

Liquid Electron suggested trying this stuff, so I first
bought a bottle of Airbrush Medium and Matte MEDIUM, thinking
that would suffice. But after a bit of reading online, there
were claims that Matte VARNISH gives slightly better results,
so I got a bottle of that to use instead.



I don't claim to be a typical artist, so I won't pretend to
understand Liquitex's system. Mediums, varnishes, flow aids ...
maybe I'll try to wrap my head around it some day.

Anyway, the suggestion was a 70/30 mix of varnish and medium and
to spray from 30-35 PSI. Since my typical airbrush and compresser combo
tap out at >30 PSI, I went with 28 PSI and used a bigger needle.

It already looks like 2% milk ...


This test was done on the underside of the saucer where I sprayed and
sanded some gray primer, then Future without completely glossing over
all the primer. After an even coat, then another light pass, here is the result:

Can you tell where the flat ends and primer begins, because it's pretty tough for me ...


I am quite impressed. It looks very flat and uniform, about on par with the
Krylon Matte and Future + Tamiya. It's a bit rougher texture, comparable to the MM Acryl Flat and ...
no interaction with the Future.

The only catch is to clean your airbrush AS SOON AS you are done spraying. Let in dry in the brush
and you'll have problems. I didn't have any issues using Windex and a little rubbing alcohol.

This is good stuff. A shoutout to Liquid Electron! I'll use it, at least what I have, on smaller
projects, so that I limit the amount of time it stays in the brush.

SUCCESS BUT WASTE NO TIME CLEANIG YOUR BRUSH.

4.) Krylon UV-Resistant Clear (Matte)
5.) Alclad II Klear Kote (Flat)
6. - tie.) Testors Dullcote Spray Lacquer
6. - tie.) Valspar Project Perfect Clear Matte


I could be testing other sorts of clears till the cows come home, but I think I've
amassed a hefty enough list of things to use for now.

I'll be posting my final thoughts and conclusions on this soon.

Cheers,
Spencer

Good stuff!  I'll keep sticking to my Liquitex. :)
