Mark Stay 2-1 Oz.

I use this with glass. I use a sharpie to draw a line where I’m going to saw glass. Then I rub mark stay over the sharpie line. The saw uses a lot of water and it will was the sharpie marking away if it isn’t covered with mark stay.

I work with Stained glass and this is a major help in my work! Thank You

First time I used it, took it to my Taurus saw, and the marker washed right off. I returned it

As above. Keeps me from having to continually re-mark pattern lines after scoring, grinding, or rinsing glass until I want to remove them.

This product has worked as advertised

Ink lines wash off when using a ring saw. I used petroleum jelly instead

Oily stains in package. Item was on its side and now it is dry and crackly so don’t know if it will work to protect the lines.
