Larry,
I didn't know there was a decent quality foam brush. I thought the whole point of a foam brush was to be cheap, throwaway and low quality.
I have always bought very good quality white bristle brushes and taken very good care of them. Wash them out and put oil in the ones i use for oil paint and soap in the ones i use for water based paint.
Is there a particular reason why you need a foam brush that a bristle brush won't do?
