El Burdo -> pumice and sanding sealer (Oct. 16 2011 13:10:10)
|
Greetings. I think I may have jumped the gun here and would welcome some advice. I've seen some of the discussions re detailed methods etc but I think my question is maybe more fundamental(!). I have bought some Rustins Sanding Sealer, which it emerges is basically shellac, alcohol and a 'special additive' to facilitate sanding, to seal whatever needs sealing. As my bridge is quite open pored I wanted to seal it before any further treatment and thought this would be fine, also good for the rosewood head veneer, the rosette and cedar neck. But now I'm wondering how, if at all, it is different from normal shellac used in French Polishing. For THAT job I have bought Liberon French polish that can be applied by brush. Have I bought essentially the same thing twice? I can't see the ingredient proportions in either product. I also am now wondering if pore filling is a separate stage to sealing. Should I buy pumice to do pore filling in addition to/or in place of the sanding sealer? Also, as a supplementary, could I apply the 'Easy' french polish using a rubber? I guess all of this seems a little unrefined, but I am on the nursery slopes of making! Thanks for any contributions and apologies for all the questions. El Burdo
