Acrylic vs. enamel (and primer?)

So, I've given up on acrylic hobby paint... not easy, as there seems to be more choice in acrylics these days.

Acrylics are not really any easier to clean up, I end up using lacquer thinner anyway to clean my airbrush. Acrylics seem to clog my airbrush more, while enamels just go through and onto the model SO much easier and smoother.
And enamels just seem more robust- harder & more durable. Could be my imagination...

Whaddya think, what's your experience?


My only problem: Enamel hobby primers!
I use Krylon/Rustoleum for the big jobs of course... but when I need to prime something small, using my airbrush, I'm at a loss... Just did a job with Model Master enamel primer... awful, had to strip everything, the stuff never cured! But Krylon went on the same parts and cured just fine... but it's so heavy it obscures details, and is hard to control out of the big can.

Anyone have a recommendation for a good reliable airbrushable primer?

Good question! I am using Krylon spray can primer too becuase I haven't found a suitable airbrush alternative. I looked at the automotive primers, but the variety is bewildering. I am still using Acrylic colors though. I thin with a little alcohol and a little airbrush medium (Golden's brand). I like the fact that it has very low VOC levels, lt works well over the Krylon. Hope someone has a good suggestion for a high build airbrush primer.

Testers primer is finer.
Also there is spray can primer for the gaming figures that is also suppose to be finer.

Acrylics are horrid (another improved and allegedly green product that is not as good as what it was meant to replace) and I have had similar issues too thin/transparent pigment-wise (I have seen others achieve awesome finishes with acrylics, just not me). Enamels are made with oil, shiny and silky smooth just like the coat of paint I hope to achieve besides, they just smell like my childhood and acrylics can never do that. I have noticed in some stores they have to check that you are eighteen to sell you a little can of Testors spray paint or glue so personally I will stick with the adult stuff and save the water colors for the kids.

Pete, and all

The latest, Low VOC, Automotive Primers, mixed properly, and shot through a "state of the art", Low VOC gun, work great! The problem is, most all of you, would have a Heart Attack, at the cost!!! I just use Automotive spray paint (in cans), WITH OUT, any primer, that works pretty good. CaptCB

I have heard that using an external mix airbrush will work better when using water based paints.

Pat,

Michigan Toy Soldier Company in Royal Oak (Corner of 11 Mile/Vermont, Next Door to Chicken Shack)

http://www.michtoy.com/

carries the Gunze line of paints plus they have Tamiya Fine Primer in a square bottle that you could airbrush/hand brush. You could call them.

However, I haven't used the Gunze line and the Tamiya Primer in a spray can has a very, fine mist, thin coat coverage and very smelly. It worked OK for me, but I had a bad surface to begin with. That was my fault. You would probably have better results.

Almost all of my models built in the last 10 years or so are painted with acrylics. I only use oil based enamels if I can't get a color in acrylic. I've had good results with the Testors Model Master Acryl and Floquil Polly Scale. I've used some Tamiya Copper on the Lyman kit with good reults. I have some good results and some bad results with Badger Model Flex. I've even used some Parma Fascolor on some Lexan parts on my latest model. I use distilled water as a thinner/cleaner for a dual action air brush. Styrene, fiberglass, and resin parts need a light scuffing with very fine sandpaper or a green pad. After adding dry transfer or water slide decals, I spray on some Gloss Cote or Dull Cote as appropriate to seal the decals.

I usually use the Tetors Acryl Primer White or Primer gray. Sometimes I used whatever older color is in my paint locker - gray, red, blue, green. I always apply several coats of primer; alternating between colors to ensure complete coverage.

I have a Monokote heat gun hanging next to my paint booth. After I spray the acrylics, I give them a quick blast of hot air . During the colder days in my basement shop, I gove the model parts a blast of hot air before I paint them as
well.

Here are some of my acrylic painted models.

Replacing a system that works (oil base paint) with one that needs a battery of special preparation steps, special application methods and careful protection after application before use is not progress.
I get the feeling that we are being directed by over qualified incompetents who want everybody else in the world to be as useless as they are.
With oil base, minimal preparation and a decent set of brushes I can usually arrive at a satisfactory and durable result. Acrylics, on the other hand, do not. However, the oil-base manufacturers seem to be using the acrylic junk as an acceptable baseline, and downgrading their quality accordingly. My experience is mostly Humbrol, I have noted that pigment solidity has gone down, and since production moved to China, they seem to be providing employment to the colour blind.

CG Bob,

The barrel back and Schnell boat are gorgeous, you are quite the prolific modeler.

Mfr,

Sadly these days a lot of things seem to be going this way.
