I needed to fab some parts for my car over the weekend. My can of layout dye had dried up and I didn't want to go to the supply store. I used some of wifey's nail polish and it worked perfectly. I can't wait to get to the shop with this fancy feminine curved bottle with the long gilded handle and start brushing it on in front of the guys. The one she gave me was a hot pink-red. Looks absolutely fabulous against the silver background of the aluminum I was working on.
