i know you have to thin enamels with thinner, but i was under the impression that you could thin acrylics with water. that seems to have proven very bad with my airbrush. i tried many different ratios with Tamiya Desert Yellow and it was horrible. i heard that i have to use tamiya acrylic thinner, is that like set in stone? my hobby store is kinda far away. what about the Testors Airbrush Thinner? i have that but it says only to use with Model Master enamels. also do i have to thin Testors Glosscote or Dullcote before spraying?
The best thinner to use with their paint is their own brand of thinner, however you can try Windex, isopropyl alcohol, or water. I prefer alcohol however it will cause Tamiya gloss acrylics to dry with a flat finish.
The only reason to thin paint is to get it to spray properly. If it sprays properly it doesn’t need to be thinned.
If I recall correctly, those are both laquers. If you are spraying them over acrylics allow the acrylics to cure for at least 48 hours before spraying the laquer over them or the laquer can dissolve the acrylic. Also spray the first couple of coats of laquer very, very lightly and allow them to cure fully before subsequent coats.
I spray Tamiya acrylics mostly and I thin them with isopropyl alcohol only. Have to test what works for you but i usually use 70/30 paint/thinner for base coats. Never thinned it with water, even my brush painting is done using distilled water for purity, tap water has to much unknowns in it.
is that just regular rubbing alcohol?
Yep …
