Boaters are aware of the sun’s harsh effects on their skin. These same damaging effects can wreak havoc on certain surfaces of the boat. The Ultimate Vinyl Guard with PTEF from Star brite might be considered “sunblock for vinyl,” as it protects against fading and damage caused by UV exposure and a harsh marine environment. The Vinyl Guard’s formula helps enhance the appearance of rubber, plastic and leather surfaces by leaving a durable, semi-gloss finish. The formula’s polymers create a barrier against UV rays and repel stains and dirt.
