12 Standard Colors In addition we can match colors and/or include flake. How is Scorpion Linings Different than other bed liners when it comes to UV Stability? Other sprayed in bed liner systems want to spray only black because if UV stability is a factor, black is the only "safe" color. Spraying a thin layer of paint over a sprayed in bed liner only offers an "egg shell" of protection. When the shell is gone, the exposed bed liner will be vulnerable to UV degradation. Some bed liner systems ask you to come back every year or 2 for a top coat. This is simply covering up a UV Stability problem. That's the reason color stability was engineered into Scorpion Linings from the initial development stages. You can't add on UV stability, you can only build it in!
