I have some Minwax brand Oil based Fast-Drying Polyurethane in Satin finish. My understanding of polyurethane is that it's all "gloss" and they get Satin and Semi-Gloss finish by adding "flattening" agents. I believe this is why the instructions say to stir before and during use; to keep the flatteners in suspension.
I rarely use gloss poly and have none on hand, but I want to use it this time. However, being cheap, I don't want to shell out $11+tax for a quart of gloss because I only need maybe 3 oz of it. Can I simply not stir the Satin before use?? Would this leave the flatteners at the bottom of the can and pure poly at the top?
I will be applying with a thinner soaked rag... yup, I'm dipping a thinner soaked rag right into the can, because that's how I roll.
