Review on Vibrant 30-Color Liquid Chalk Markers by Positive Art: Perfect for Kids and Adults, Painting, Drawing, Window and Board Art at Bistros and Bars - Reversible Tip with Cleaner Set Included by Amber Perez

I was looking for information on using this paint for chalkboards before purchasing - I couldn't find anything about it. We primed the surface and then applied 3 coats of chalkboard paint. The chalk works great with it - easy to peel off etc. We thought lighter colors would be great - so we got this. We have a set - markers, cleaning spray, erasing pad and napkin. The marker does not rub off even with a spray. Luckily we made a test area in the corner first and the only way to get rid of it is to paint over it with chalkboard paint. I hate giving 1 star because in other apps this could be a great product but it is NOT. Use on panel painted surfaces.
