Despite contrary opinions, spin coating can work well. My father used this
method years ago when he made albumen emulsion plates working in the
Blueprint business. The problem is that it is difficult to coat large
surfaces and to control thickness. Make sure you test all the variables.
You might also consider buying a motor and mounting it in a plastic or
metal tub. That way you can add a lid or ideally, a clear Plexiglas cover.
I also know someone who coats ceramics using this simple method.
