I try to avoid clearcoating unless a model actually requires it (eg. showcar) or I'm trying to improve a less than perfect polishing (looks good but....)
My clear of choice is Tamiya acyrlic clear. It doesn't yellow and polishes nicely. My problem is that I can never get the stuff to airbrush correctly unless (weird exception) the shape is highly curved (eg. Paddy Wagon fenders, Harley fuel tanks etc).
Here's the problem that hopefully someone can explain:
When airbrushing the clear it rarely flows like normal paints. It mists fine but when you go for the wetter coats it tends to slightly bead up and eventually create a less than level coat. The beading isn't much but it's enough to be a pain that demand a thourough polish..
What could I be doing wrong?
Paasche VL Regular pressure settings (approx 14psi) Thinned with my usual homebrew thinner of 50:50 IPA and H2O.
The clear is usually going over Testors Enamels but that's not always the case. Same results though.
Am I over thinning, need a flow agent, should try a different technique?
