Plasticmod992: A question (or two), er, ok more than two...

Hi Greg,

I just re-read your replies to Mike V.'s queries on Tamiya paints, in which you advocate the use of Denatured Alchohol ("DNA").  Do you use this as a thinner for the paint?  What has been your optimum mixing ratio, or does this vary by reflectance (eg. more for gloss, less for flat).  Also, if I have not misread the thread, do you also use "DNA" to clean your airbrush/accessories?  Would DNA also work for Gunze Aqueous paints?  Have you (or anyone else) used "DNA" with Modelmaster or Valejo paints?  Sorry for all the questions, just been having problems with all acrylic paints lately: tip dry with Valejo metallics thinned with Valejo thinner; Gunze paints not thinning well or "gunking up" (for lack of a better term); lack of coverage by various manufacturers paints.  If it helps I am using an Aztek 4709 with a Testors blue compressor (not the mini but the next step up).  I also have a Paasche VL (?) double-action but to date  have not used the later as I do not know if the compressor has enough "oohmppf" to drive it, plus I am a little afraid of really goofing it up.....-sigh-  Thanks very much in advance for your help!

I Addressed much of this in my post "Painting with Tamiya acrylics" here if you want to take a look. Wink [;)]

Elfkin - you can't use alcohol with Vallejo, it is a water based acrylic.  It will basically cause it to turn grainy in the paint cup.  (the same thing happens with Tamiya thinners)  You might try some retarder added to the paint, you can get it at art stores and craft places.  Some brands include Liquitex and Goldens.  They are usually are named things like "Liquitex Airbrush Medium" or "Liquitex Acrylic Retarder" (or Golden's depending on which brands are carried by the store).  Just read the bottle and it will say somewhere on it "To slow drying time of acrylics"  That's will help some with the tip dry.  Don't use too much maybe a drop or two or the model will never dry!

That said, the DNA should work fine on the Tamiya and MM.  What does Gunze recommend you thin their aqueous line with?  If it is distilled water, then you'll want to follow the same guidelines as the Vallejo.

Tom,

I will try DNA with T/MM Acryl and get back with the group here.  God knows I've tried everything else under the sun to get Acryls to work right.

Greg - I believe someone mentioned thinning their MM with ISA somewhat recently (leading me to believe DNA would do well), but would be interested to see the results all the same.  I've pretty much switched over to Vallejo totally but still have a sizable stash of MM....

I'll be testing the combination tonight and post the results.  Ofcourse, if anyone else gives it a go before I do..please report back.  It would be a great revelation if this in fact works, as I so desperately would like to use the Acryls successfully.  The availability and color selection alone would merit a total switch if it does.
