Severerlt bad plastic rear window - anyone offer a temporary method of improvement? - 986 Forum - The Community for Porsche Boxster & Cayman Owners

The rear plastic window in my '02 S model is virtually opaque. I have a complete 2003 top that I bought that I'll be installing on the car in the coming months so that I can have a full size glass rear window, but I have so much to do on the car until then that I was hoping that there is a way to make a temporary improvement so I can at least see through the darned thing. It's very cloudy, and around the edges it looks almost like there is some sort of mold on the window. Is there some sort of drastic procedure available that can help improve this on a temporary basis? I tried Plast-X ( I believe that's the name). The window just laughed at me, no improvement at all. Rubbing and rubbing on this thing got me nowhere other than a sore hand and arm. Any stronger chemicals or a procedure using some sort of power tool, or both?

edit - trying to fix misspelled typo in title, so far no luck.

A local indie eurocar shop here swears this stuff works, so I'm going to give it a try.

Doesn't cost much and probably won't make the window any worse.

Btw, I can think of funner ways to get a sore hand and arm!

Just drive top down, best rear visibility!

I obtained a very good result with this: https://www.novuspolish.com/
Check fleebay for deals.

Follow the instructions.

Good luck

I ordered both products, lets hope that at least one of them helps!

I can vouch for the Novus---it does a pretty decent job.

The other stuff? IDK...not exactly glowing reviews. 1 OZ???

Any good plastic polish (3M, meguires etc.) , a good soft terry cloth towel and lots and lots of elbow grease on BOTH sides and you should improve it. Did I mention lots of elbow grease?

The Kit that includes Novus 1 and 2 and 3.

3 is a rough texture cleaner that scrapes the top layer with the yellowed color off the window, then 2 a finer roughness cleaner and then 3 a polish. Do the inside of the window too but without the rougher. Then maintain with the polish. Extended mine's life for years.

Oh, might need to give that a shot. Mine is in pretty good shape overall, but does have a few scratches etc. Would be cool to be able to polish it. I've been using a good UV vinyl protectant on it. Seems to do an ok job. But to get it a bit more clear would be really nice!
