chark marks

[sixbangr]

I did a flame layout useing a stick of chalk, I didn't know about the pounce wheel. How do I get rid of the marks? I have tied thinner, wax remover and soap & water. It is on epoxy primer. thanks

I use a 50/50 iso-alcohol/water mix and a lint free cloth. What kind of chalk did you use? I use regular (cheap) white school chalk. TC
