I just wanted to double check ony foam bushes. They say "not for shellac and lacquer". I bought them from CLC so I assume that they are OK for varnish. 

I just finished what I'm hoping is my last coat of epoxy on the bow and will be moving on to the deck tomorrow night. So before I start into the varnish  portion I wanted to make sure these brushes are OK. Sorry if this is an obvious question to some but I am a total wood nube and would rather be safe than sorry.
