RE: Epoxy or Polyester???
Has anyone read the warning label on MEK, scare the heck out of you. I worked oilfield as a young man and got bathed in MEK once when a drum got dumped on me, burned like heck. Glad I didn't know how dangerous that stuff was when it happened, I might have freaked. Maybe that's the reason I got cancer years later, hmmmm.
Sorry if this statement was a bit off topic.
