Why is it so important to get Pro-Tek-Tor to penetrate?
Allowing Pro-Tek-Tor to penetrate deep into the surface of the wood enables it to fill and bond to the cells of the wood. UV damage is usually only microns deep behind clear or transparent finishes. This damage is what causes surface film finishes to lose their bond to the wood. When Pro-Tek-Tor is able to penetrate beyond this depth, UV damage is greatly reduced.
