The foam brushes used to be better
The problem is that you only notice the defects when you urgently need the parts. The brush edges on all the brushes delivered were poorly finished ("frayed"), which led to very poor finishing results. Furthermore, the entire foam came off the backing after just a few careful brush strokes. If I order again at all, I'll do it much sooner before the work to allow for any potential complaints.
Just a few years ago, the brushes were much better made and more securely glued to the handle.
