I have a red mahogany stained front door with a coat of polyurethane on it. Recently I had to re-stain it and put another coat of polyurethane on it but after the polyurethane dried I realized that the stain ran in a couple of spots. What is best to deal with those runs, steel wool or sand paper 220 grit?
Also if I don't like a spot where I stained and poly'd over that, what is the best way to prep that spot to stain it again and reapply the polyurethane over that ? One last question, based on your experience, what should the minimum temperature be for doing this stain/polyurethane outside (this might be on the can but just want to hear it from experience)?
