I agree...I find dry chalk a mess and does not leave a clear reliable mark. Instead I use lumberyard chalk powder, the stuff you use for carpenter chaulk lines. Make a paste with the chaulk and water and brush it on. Works better than anything else I've tried yet. Red is more color fast than the blue.
