Polymer Solutions did a demonstration site for us free of charge. It is a permanent solution to fading backing boards using UPVC strips with high reflectivity tape. We have not used it anywhere else as all our backing boards are fitted with reflective tape anyway. Polymer Solutions say they use a higher grade of tape than our standard but whether it is worth the extra expense is debatable.
