I actually prefer lightweight silkspan available from SIG. A lot of top guys prefer Carbon Veil. Either one works well with dope. For me the silkspan is a little eaiser to work with and seems to take less dope to fill, but I'm sure there are folks that feel the opposite. If the Carbon Veil is used it should be the "light and fluffy" type rather than the stiffer stuff that actually looks better but is difficult to work with and sometimes develops a lot of pin holes that are tough to fill, get some filled and others open up!
The carbon is supposed to be stronger but applied with dope and sanded I'm a little skeptical that is it!
I just cover everything wood with lightweight silkspan and dope then fill with dope and talc.
I don't do front row finishes but good ones.
