Older exterior plastic trims that have started to look tired and faded can sometimes be difficult to rescue. Why? Because age-related weathering strips out oils and damages plastics permanently. Trim dressings only mask such problems, as opposed to fixing them. The trick then, is to use a product that replaces the lost oils as opposed to simply masking the signs of age, and which lasts for as long as possible, thus reducing the reapplication frequency. Nanolex Trim Rejuvenator uses nanotechnology to deliver an expected lifespan of up to twelve months per application, which is ten times longer than most trim dressings. It also does an excellent job of rectifying fading, and imparts an as-new satin finish that does not run or streak when it gets wet.
