IApplying Spaz Stix Surface Pre-Prep is an especially important step when using Spaz Stix Color Change paints to finish your polycarbonate R/C body. Using it prevents swirls caused by static electricity from the body, and improves adhesion. Apply in one very light coat (barely a mist) before spraying your color.
