Model Master Acryl Trouble
Posted by scalefly on Wednesday, January 30, 2008 7:25 PM
I applied Model Master Acryl Flat Clear over a base coat of Tamiya and Gunze paints, and it turned to a transparent white haze!  Any ideas what may be causing this and more importantly any ideas on a fix?  This was the finish coat on the entire deck of a 1/350 Titanic which equaled lots of hours!  HELP!

I know Testors recommends only light coats of Acryl Flat Clear.  Too heavy of coat will result in frosting- been there, done that.  I don't know of anyway to fix it.  Maybe you can try some gloss coat over it.  I actually stopped using Acryl Flat Clear for this reason.  I'm currently using Tamiya's Clear with Flat Base added.  What was your base paint?  Any chance of stripping the Clear?

Sounds like it wasn't properly mixed and ended up with too much of the flattening agent. Sucks, but like will require a complete restrip and paint. I feel your pain!

So long folks!

thanks for your input, but thankfully some Future came to my rescue and I was able to recoat the entire area which made the hazing disappear!  I think I'll go to church this Sunday!   I will make sure to test that mix before applying it to a finished model!

I was going to suggest that (no, really!) but didn't know if it would play nice with the MM clear. I've salvaged hazy Future coats like that.

Congratulations on pulling it off! 

So long folks!

I've had Future haze when I added too much Tamiya flat base.  The remedy was just to add more Future to the mix and reshoot.  Good to hear it'll fix MM too.

Here's a simple solution. Get some MM semi gloss clear coat and add to the clear flat. Takes care of the whole hazing, fuzzy issue. 2 parts semi gloss to 1 part flat.

Here's Swanny's ratio chart from his Complete Future article:

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.

 

So long folks!

This is due to the type and quantity of flat base in the paint. To much flat coat on top of your paint and flat base becomes "visible" and looks like frost. I get the same thing when I mix Tamiya flat base with future as a flat coat. Try thinning your flat coat more and be sure to not spray on more than you need.
