I have used Red Tree foam brushes for years to apply high gloss spar varnish with very good results. The brushes held up for multiple uses and cleaning with paint thinner. Most recently, I have seen a change in the durability of the brushes. The last batch of Red Tree brushes I bought (about a year ago) only lasted a short while before the foam fell off the plastic stiffener. I suspect there may have been a change in the quality of foam or glue used to make the brushes. They also did not hold up well when applying Interlux Bright Side one part paint. I still plan to buy Red Tree brushes on my next box.

Planned to use them for varnishing. Big mistake. They are not worth the extra money. They are too spongy to control the flow of paint or varnish.

Head breaks from the handle under little pressure. The connection point of the foam head to the handle is weak. I've been looking for a decent foam brush and I had hoped these would be good based on the web site, but theses were not what I was hoping for.
