Duplicolor primer thinning
Posted by DMack on Thursday, February 29, 2024 10:48 AM

I am building 1/144 resin aircraft and, based on a recommendation, will use Duplicolor Filler Primer. Coverage straight from the can is too broad, so I plan on decanting it & running it through an airbrush (.3mm). Question - how much should it be thinned? "The consistency of skim milk" is not helpful.

I could be wrong but I suspect that not a lot of people here in this forum have done the specifics that you ask about. IE that particular Duplicolor, decanted, further thinned in exact ratio, sprayed to resin through a .3 tip to a small scale resin model.

I've decanted Mr Surfacer 1000 personally but never the Duplicolor Filler Primer. And I decant it for part of the reason you mention, more precise control of the spray pattern. I also use the bottled Mr Primer Surfacer 1000 and thin that about 25% with either lacquer thinner or more likely Mr Leveling thinner. The bottled Mr Primer Surfacer is already fairly thin in the bottle. Well this isn't helping answer your question, perhaps !

That said, a place where Duplicolor paints, including primers, comes up quite a bit is over in the Model Cars Magazine forums. In the General Model Building Questions and Answers sub forum.. You might try there if someone doesn't come along here. Ya, it's a model car forum but they use resin there and Duplicolor from time to time. There are some die hard Duplicolor folks there actually.

I've used decanted Duplicolor and Rust-oleum primers on a lot of my models. Once decanted I thin it 2/1 no-oder turpentine/primer and use it in my Iwata Revolution CR Airbrush with a .3 needle and 20# on the compressor. Used the White, Grey and Black primers wih the same set-up and have never had any problems.

Hope that this helps.

Stay safe.

Thanks, I'll give it a try.
