CW,

I am a fan of paint too. I no longer glass the surface tho. I use silkspan and dope it down with nitrate dope. It is thinner and much lighter than glass (even the 0.5 oz variety), on par with plastic film when fully painted. Consider than none of these finishes are thick enough to provide any hanger rash protection, neither glass nor silkspan. So why use glass?

Light silkspan requires some special handling skill to lay down but works well. It may be simpler to start developing the skill with medium silkspan...much easier to work with
