Just sprayed slick sand for the first time and got tunnel vision while adding the activator. Four tubes for a gallon. Got one of the tubes out and was noticing it had marks on the side of the tube in 1/4 increments. Long story short I added activator like one tube was for a gallon. Only have 1/4 the amount of activator. How do I strip this mess off? Rags and acetone?
