About this product range
SPI Universal Clear 2.1 VOC is a 1:1 clearcoat system for spot repairs and overall refinishing. Mix equal volumes of clear and the specified activator. It can be applied over basecoat and activated single-stage finishes; allow a single-stage finish to sit overnight before clearcoating. The manufacturer recommends a 1.3–1.5 mm gun tip. Choose the activator for the job and follow the specified flash and drying schedule.
