That is not what we like to hear! Our FlexiDip Removable Rubber Coating should spray evenly from start to finish. It sounds like solids may have settled to the bottom of the can, creating either a partial clog or inconsistent spray pattern. We recommend shaking the can thoroughly prior to, and frequently during use to ensure an even spray pattern. If this does not solve the issue, please give us a call at 800-481-4785, we want to try to make things right.
