I recently decided to try a stain-poly mix when I was finishing a couple of projects. My problem is that I can not eliminate brush marks from showing in the dried finish. I have tried 4 times now to get a final coat on but each time I get a few brush marks which mar the appearance. I am about ready to give up and just top it off with either a wipe-on poly or a spray poly. Anybody have any luck using the stain-poly mix?
