To ensure maximum adhesion on all surfaces, lightly rub stripper into surface using a brush or a cotton bud. Make sure to test on small area that will not be noticeable. Allow stripper to dry completely (usually 10 minutes, depending on temperature), and repeat 2 to 3 times. Do not be alarmed if color is removed from surface. This is a cleaning and deglazing agent. Only use where paint will be covering.
