Spotted discoloration when spraying Ammo Mig Acrylic

Ah Interesting - I used model air before also and it just worked for me no problem. So many diffrent paint choices! Its cool though that we have these options.

I watched the video intially but yes was a little hard to understand. After sparying and having a bit of practice I watched the video again and it was much clearer to me what was involved for sure. I did indeed use primer. I haven't got any thinner as I only have the one bottle and it does say it can be sparyed "straight from the bottle" - but I don't think that is the case... not with my airbrush setup anyway.

Next time I spray I will defintly use the proper thinner. The saftey aspect of these paints does appeal to me (compared to Tamiya etc) so am thinking of investing in more.

 

Each brand has it's learning curve and once you know the brand you know how to handle it. But honestly and just fwiw, I've never seen anything with the cratering and all like they showed in the Mig video from Vallejo Model Air. I like how Model air goes on. Course then you could be into another product line lol. and I've seen complaints on that choice too. It's all in what you get to know. Just sayin.

I watched one of the videos as well, having never used the ammo line. One of the first two things brought up was primer and then don't thin with water but use their water based thinner. And finally to apply the paint in several light layers vs wet coats. Heavy wet coats go on uneven and causes cratering. He did one test shoot with 30% thinner added and to me the results looked great over grey primer.

So I'm gonna say to order in some thinner at least. To me, and especially with acrylics, primer is a given so I assume you primed your parts. If not, then why not ?

The presenter of the video spoke severely broken English but I heard him say clearly you need to be patient and follow the several light coat theory and you will get good results. He stressed outright that this is not Tamiya or Mr Color acrylic which are not true acrylics but more a form of lacquer. Mig Ammo is 100% acrylic and takes a different technique to apply.

Hi All - I attempted to spray this again and after a bit of stuffing around I would say I got an acceptble result.

I *think* it may have been a technique issue. I practised a bit with plastic forks but was still getting the same result. This was after stirring (cap came off really easy) and thinning (albeit with water as I don't have mig thinner)

I also watched the problem solver video which showed that the acrylic could come unstuck from the surface if you don’t paint a very thin surface coat first  before scaling things up and adding more color. I noticed that was what was sorta happening with the fork. 

I was then able to get it working okay using that technique + very slight thinning.. although I’m still not 100% sure that was it to be honest. I must admit that after all that, the colour does look great once it's on so its tempting to try using it again on other parts etc.

You didn't mention thinning. If you happened to use Tamiya thinner with that paint, that may be your issue. Just a thought.

I don't have a whole bunch more to say from the others but from the photo supplied it looks to me like the paint needs both better mixing as well as a bit more thinning. Then it should spray well. This assumes proper needle combo and air pressure.

Ya know sometimes I've tried a combo and gotten a bad spray pattern, thinned more and all was well. Other times I kept thinning and still lousy, dump the paint and find the brush won't even spray bare thinner properly. IE the brush needed cleaning or a seal was leaking. So when my brush has been sitting a while, these days I go right for a few drops of thinner and make sure it at least sprays that normally before even putting in paint.

Okay interesting. Few things to try. Will let you guys know it a couple of days. Thanks heaps everyone

You can’t actually open it to stir the contents of the bottle.

Unscrew the cap, then gently push the tip sideways. The edge should lift enough to get under it to pull it off. Then use a thin rod to stir.

I struggle with acrylics - bit of a learning curve I suppose.  Also - maybe consider washing the parts if you didn't.  Watching for a solution.  

Looks to be a problem of not thinning it. Look at Mig's youtube problem solver.

You may need to actually stir the pigment at the bottom up to get it to mix well. Try that and see what happens.Get right down there and get it loostened up, then shake.
