Removing Plastic window scratches

[Perfectlap]

Well I use Plexus to keep the back plastic window crystal clear but it won't remove the hairline scratches and bend marks. For that I'll be giving this
Renovo Plastic Polish a shot. It was recommended by one site over their Meguiar's product (even though he didn't carry the Renovo product). Must be good.
I plan to apply it to my de-Ambered headlights before I add the stongard vinly headlight protectors. These plastic headlights and windows are not cheap to repair..
By the way if you have tinted windows Plexus is also the recomended product.

Believe it or not, a good item to use to buff plastic headlights is..... :dance:
REGULAR CREST TOOTHPASTE The floride in it is one of the best things u can use (reason they use it for teeth). I've used it on headlights and motorcycle wind sheilds. works wonders.
Do not use any other kind, especially "whitening" it will scratch the hell up plastic.

Regular Crest Toothpaste has the most purest consentration of floride compaired to the rest. "Whitening" has crystals that can and will scratch plastic. Other brands have a different gel like substance that can cause cloudiness.
Its basic chemistry guys :dance:
What do you think the dentist uses to smooth out and clean your teeth with?

This is a great tip. Based on my empty-the-medicine-chest-and-travel-size samples testing, all the following did a good job with no scratches added*:

• Tom's of Maine "Natural Tartar Control & Whitening"
• Arm & Hammer "Complete Care - Intense Freshening + Whitening"
• Colgate "Cavity Protection - Great Regular Flavor"

*My test sample was an old pair of plastic glasses... don't know if this is representative of the plastic on our favorite cars. When I tried the same pastes on an old CD there was some fine hazing from all 3 (least from the Tom's), so I guess it depends upon how soft the plastic is or what type of plastic.

As a comparison, I tried the same thing with the Porsche "Polyglass Window Cleaner" and also the 3M "Finish Restorer". These two products seemed to cause no hazing on either the glasses or the CD, and the 3M product even appeared to be able to remove the hazing left by the other products from the CD.

hrrmmm..."Whitening"....I've always have had bad experiences with that because of the crystals... "Whitening Crystals" tend to scratch thus causing the "haziness"
Which is why I reccomend "Regular Crest"

Let me second the Crest recommendation. It's the same thing as jeweler's rouge, but far cheaper and minty! lol I've been using it for years on plastic wristwatch crystals and marine cavnvas windows and it works a dream.

Careful with the Boxster's headlights though, as they have a coating that you don't want to craze. I'd just live with scratches there.
