Rear Window:
The fogging on polyvinyl occurs when the plasticizers in the material evaporate due to UV radiation and heat exposure. The plasticizers maintain its softness and flexibility; a good plastic polish (Plexus) will remove scratches and the fogginess and maintain its flexibility.

Place a 100% cotton cloth (front and back of rear window) when the top is down, this will help to avoid any surface friction scratches and prolong its durability. This will also avoid any transfer of product to the rear window from the tops fabric dressing. Avoid putting the top down when the material is damp or wet as this encourages mould and mildew to form

The material used for the 'plastic' windows in convertible tops, soft-tops, is a specialized type of vinyl called 'Pressed Polished Sheets'. This material is actually composed of two layers of non-colour vinyl laminated together under intense pressure and high heat; this process squeezes out all the impurities and renders it optically clear.

Acrylic plastic - wipe with a damp towel, then spray a clean a damp 100% cotton Alpine DF'M Microfiber towel with Plexus® use a light to medium pressure on glass surface, finally buff with a dry Autopia ConcourseTM Buffing Towel

Glass- wipe with a damp towel, then spray clean, and damp 100% cotton Alpine DF.''M Microfiber towel with StonersTM Invisible Glass, finally buff with a dry AutopiaTM Concourse Buffing Towel

Removing Oxidation (polycarbonate):
The rear window starts to exhibit an opaque appearance and then a yellow hue on the outside. Original equipment material (OEM) suppliers started to add a UVR protection to the surface in an attempt to reduce this condition and prolong the usable life of the polycarbonate.

While most of the cloudiness is on the surface, severely discolored polycarbonate cannot be brought back to optical clarity. If you live in a southern state, this discoloration can become noticeable in as little as two-years.

Novus 1 - gently cleans all plastics without scratching, leaves a lustrous shine that resists fogging, repels dust, and eliminates static.
Novus 2 - removes fine scratches, haziness, and abrasions from most plastics (exceptional for removing scratches from Plexiglas). Use repeatedly and restore faded and discolored plastics.
Novus 3 -removes heavy scratches and abrasions from most acrylic surfaces. Contains abrasives, not for use on eyeglasses, polycarbonate, or coated plastics, final finishing also requires the use of Novus 2
