I've also used Isopropyl Alcohol whenever I dribbled rod building finishes and epoxies on my work slacks. The trick is getting to it FAST, as you did. I would recommend that you get an apron, but I have 3 in my workshop that I never wear. I'm afraid I might spill something on them. Stains or spots of glue on my slacks are one thing (they are only pants), but a dirty apron? Well that just looks sloppy.... There's logic in there somewhere... I think.

If you want an apron, I'll send you one of mine. Outside the dust, they should be fairly pristine
