Hi all, can someone help, I intend to use Vallejo metal paint then put a Vallejo metal varnish on, my question is two fold I need to paint some parts Vallejo color or Tamiya paint or washes, so do I do this first then put on Vallejo metal varnish or afterwards then what varnish do I use Tamiya, Vallejo metal or just the ordinary Vallejo varnish. I getting totally confused.
