Thinning Tamiya xf-86
Posted by JerB on Saturday, January 16, 2021 11:27 AM

Hi guys

i was asking this in a thread I have in the general discussion forum but thought it might be handy to ask here so people might find it later if they have the same question.

im curious as to what ratio of tamiya xf-86 to tamiya x-20a I should be using ?

any tips would be awesome

I can't really give an authoritative answer on that, since I have yet to use XF-86.  But, if it behaves like the other Tamiya acrylics, I'll take a stab at it.  I have kind of a "different" way of mixing my paint, since I like to make sure I get a complete mix.  Before my Tamiya paint goes in the airbrush, I like to transfer it to a small paper dixie cup using a party straw that I cut in half to use as a pipette.  After using my Badger electric paint stirrer, I'll put 1 or 2 straws worth (I dip the straw in the paint to bottom out in the bottle, and then put my finger over the open end) in the cup.  Then I use a small, glass syringe to get thinner from one of my many thinner bottles to transfer to the cup.  For Tamiya acrylic bottle paints, I've been using 99% aviation grade isopropyl alcohol as a thinner.  The ratio that works best for me with that is 0.5-1.0CC of thinner to each straw "pipette".  Then I mix it in the dixie cup with a wooden skewer before pouring the contents into the color cup of my airbrush.  To be sure I have a good mix and spray pattern, I use sticky notes to make a couple of quick paint shots before moving to the model.

I thin it the exact same way as I do for all tamiya acrylics.  I thin 2 -1 (paint to thinner). I put the thinner first in the paint cup of my airbrush (I use a pipette and count the drops, ensuring an exact mix). I thin add the paint (clear in this case), using the pipette.  I then stir in the cup, and do a little back flush, and shoot at 20 psi.  Works perfect for me every time!

Oh, OK, the clear flat.

I’ve only used the stuff a few times, but I’ve found that more thinner  equals less flat in the final appearance. Something like a 2 to 3 parts XF-86 to 1 part thinner gives a flatter finish.
