PPG Concept activator

[Troy Newman]

Stick the activator in the refrigerator after opening...It works...I have 
some over a year old after opening and just used it about 6 weeks ago.

One note...Let it warm up to room temp before you use it!

Also the DCX61 is available in smaller amounts...Pints instead of Quarts...I 
could never get the DU hardeners in Quarts...Plus the mix ratio is much less 
so its more critical...The DU's were dummy proof IF you mess up the ratios 
on the DCX61 it will not cure right....There is some swag...but when its 
mixed at like a 4:1 instead of the old 2:1 it becomes more critical...I 
think these are the current mix ratios....Also I have played with reducers 
to adjust cure times too.....I'm not a paint expert but have learned a ton 
in the last couple years...Now If I could just get a good clear job I would 
be thrilled....

I'm using DCC (concept for the white and then DBC (base coat for the colors) 
on top of it and it works really well. Light too...My latest was a CA models 
Eclipse and I used less than 4ozs total primer, filler, Lettering under the 
clear, and clear. This is pretty good....And I think I can do it 
lighter...But my clear jobs are not up the shape I would like.

Trying to use the 2020 which I'm out of now...So its 2021 or the 2042....My 
problem has been dry spots where the paint is drying too quick...I think I 
just need to lay it out and use more paint but worried about runs and 
sags...

Suggestions on which clear to use? 2021(high Solids similar to the 2020) or 
the 2042 Speed Clear?


Next question speaking of paint...Anyone try using some lacquer based paints 
like the Plastic model stuff (testors or Pactra) for highlight colors like a 
silver fade or small stripe and then using the Concept clear over the top of 
it?

I'm trying to get Fancy with the cheese wiz and adding some effects to my 
Flashdance for A.A stuff....Need to figure out without buying little qty's 
of the Concept...If I had 4ozs it would last a life time in the amounts I'm 
looking at....I know Tony sells 4oz at a time for limited amounts...but 4ozs 
would be a 380 airplanes using the qty's I'm talking about in my airbrush.



Thanks for the advice from the Paint experts.

Troy
