When adding a veneer and glass over carbon how thin should the glass be? I don't want to make it to thin. Any help would be appreciated.

I think most guys try to get it down to .o10. It is a lot less trouble to just put the carbon out on the front with no cover. And add a purty veneer on the belly.Anything over the carbon makes it less effective.

If you put carbon only how thick is the carbon?

No ones put carbon on as a skin.
