“This product did what I expected, on the second attempt. I learned that the bottle really does have to be shaken; in fact it benefited from being left standing on its head for several hours, then thoroughly shaken.
After applying the fluid I left it to completely dry before attempting to rub it off with an eraser and it came away cleanly.
I found that the brush I used was easy to clean.
The fluid met my expectations and was competitively priced.”
