Probably for similar reasons.
- Wife hates the smell of enamels.
- Acrylics wash up with soap and water.
- Acrylics are easier to remove when I screw up (often).
- Acrylics have less volatile organic compounds that cause allergies or healt concerns
- Wife really hate the smell of enamels (arguable).
- I use Tamiya exclusively, as I find they airbrush fantastically. Brushpainting is a bit of an art form.
- Did I mention that the wife really, really hates the smell of enamels?
I'm not familiar with the Testors lineup of Enamels. They don't list a "buff".
Tamiya XF-57 Buff = FS 33531. The Model Master FS Enamel line doesn't seem to list that color, but the FS cross reference at IPMS Stockholm shows Model Master 1706 Sand is close. To my eye it's too yellow.
Humbrol 121 Israeli Pale Stone is closer. I can't find a Testors match, so you weren't kidding you didn't know BUFF!
