Designed for aerospace and aviation, 303 is the World′s most effective UV screening product. It restores & maintains a like-new appearance, texture, and color to your spa acrylic. For maximum UV protection, reapply 303 Aerospace Protectant every 3 to 5 weeks of exposure.
Using the towellete, apply 303 to the area requiring protection, most importantly any acrylic surface left exposed to the UV rays of the sun. Then with a clean non-abrasive absorbent cloth, immediately wipe the treated area COMPLETELY dry!
