Yes and yes, the two work perfectly together...in fact that's what i did myself. The firmness is on a parr with Winsor and newtons "Winton" range which i used to use all the time and which were thick enough for wet on wet application.
I now use Winsor and Newton "Artisan" water mixables which i use in conjunction with Artisan linseed oil, if using Bobs liquid white the brush used to apply it will need to be cleaned with spirits....Hope this helps! 😄
