In the case of opaque plastic and urethanes left exposed and dirty, where the surface is eroded and oxidised, dried out and faded, you can revitalise it with a plastic restorative agent. Mothers® Naturally Black® Trim & Plastic Restorer is a good example of a formula designed for this purpose. Repeated applications over several days can help to bridge the gap between tired or sunburned molecular bonds. When washing your car, you may notice that exterior components (such as trim, moulding, bumpers, door handles, vents, seals and others) have faded from black to grey, their surface crispy and cracked. This is where restoratives like Naturally Black® shine (pun intended).
Note: once plastic has deteriorated so much, lighter chemicals like Protectant can’t save it anymore. At this point Naturally Black® is the only best option. New to the range is Mothers® Naturally Black® Heavy Duty Trim Restorer which can erase years of neglect and deterioration as a first step to revitalize your trim pieces.
