plastic rear window polish

[Elliot Cannon]

Newbe here with a probably newbe question. What are people finding to be the best stuff to use to polish up the rear plastic window?
Has anyone replaced the plastic window? I'm guessing a new one would have to be sew in? Does the top have to come off? Maybe I should get a new top with a glass window?

Cheers, Elliot

Novus 1,2,3. Kit. First you use the most abrasive then the middle and once you have removed the glaze you use the polish. Use inside and out. Inside you have to be a contortionist or really small. I only user the most abrasive once and then used to mildest (I forget how the numbers go, 3 bottles) every 6 months.

Yes there are a few shops that replace the plastic windows and a very few that can do it with the frame and top together.

Most people just replace the top and there are several companies that sell a glass version. Don't underestimate the amount of work for a new person to do the top replacement.

I would love a zippered rear window...like the old MGB's use to have...But I dont know any companies that can install or sew a zippered window in..

I've used the Meguiar's product as shown in the video and I can attest that it does work, even if by doing by hand and with some level of medium effort. I did notice an immediate change, so I imagine having a polisher will yield favourable results, as evidenced in the video.

My biggest fear, doing it by hand, was applying too much pressure on the plastic window and completely destroying it. I'm now convinced the polisher is a safer option.

High there.
I am new to this but live in the UK.
I have had a Boxster for 3 years and the rear window split so needed replacing. I simply went on line and found a car upholster who fits them. (only 50 miles from our house)
It was £ 300 fitted and took him less than 3 hrs. (he had done many before). Yes he had to remove the lining from the mechanism, but fitted it back just fine and have had no problems since, and can now actually see out of the rear window.

Hope this helps.

Meguiar's products worked well for me too. I started with their number 17 Clear Plastic Cleaner followed by their number 10 Clear Plastic Polish. Instead of using an electric polisher, I did all the work by hand because I thought that I would be less likely to get the compound on the cloth top that way. The project wasn't especially quick or easy, but the result was better than I had expected. Here, take a look...

I'll be trying this stuff but I'll use a (cheap) small diameter electric buffer. Harbor Freight is about 5 minutes away. I watched a video (don't ya just love utube)? This fellow masked off the top materiel with regular blue painters tape.

Here is a before and after, after about 5 minutes of buffing with a small cordless buffer.

It seamed to do a pretty good job of on the "Boxster Crease". Like I said, that was after only about 5 minutes worth of buffing. I'll spend more time on it tomorrow.

Did you polish both sides, how did you do the inside?

So far I have only done the left side for comparison. I'll be trying different products as well. I haven't even tried to do the inside yet.
