There is no reason why you can’t use cheap throwaway or foam brushes for jobs where the quality of the surface does not matter. Putting on stain that will be wiped off is a good example. Those foam-on-a-stick brushes are great for putting down the first coat of primer or oil varnish. For anything that requires a smooth layout with no brush marks and no hairs in the finish, good brushes are an important investment. You’ll appreciate the difference. Try A Purdy XL Glide.
