Finally I can get a word into this debate first started by Doug Pauls:
I recommend the use of bare wood (unvarnished) pure sable artist brushes
from a reputable manufacturer. Why?
1 They resolve ESD issues
2 Plain wood so that there is no risk of paint or varnish "contaminating"
your work
3 Pure sable because, looked after properly, they will all but last
forever - ask Michelangelo...
4 The "crimp" needs to be as secure as possible to minimise hair loss (ooh
I can just see the fun you can have with that remark)
If you are doing stripping and localised "cleaning" (OK, dirt
redistribution) then pure Hog Bristle works best.
Such brushes are available from Concoat/HumiSeal and no doubt others....
