How to Clean the Plastic Rear Window: BMW Z3 

Good morning from California. I will be washing my Z3 within the next hour. Great to see your video. Hope your Memorial Day weekend is relaxing.

Thanks for the informative video! Well done!

Great job

I've been using the Meguiars Plast-X on my Z3 rear window and headlights on all my car's for years. However I found another product that really compliments the Plast-X cleaner when applied afterwards, 3D Poxy. I've used the 3D Poxy to wax my Z3 and the results are amazing, deep luster, no swirl marks, easy on and easy off is always a big plus when waxing. While cleaning the headlights on my wife's Edge (outside car / guinea pig ) with the Plast-X I thought what would happen if I followed it with the 3D Poxy? The results were amazing, just like it came off the showroom floor!!! So I decided to give it a shot on all my car's including my Z's, same result different car's. I then had the courage to use this product ( Plast-X 1st followed by 3D Poxy) on my 24 year old original Z3 back window and again the results were amazing, just like new. Just for the record: I'm not affiliated with 3D Poxy in any way shape or form and not receiving any royalties. I'm just passing along my delightful experience with the product and the amazing results, Carry On...

Just bought my z3 - $4500!! Needs some paint and a clutch. But happily driving my 120k mile 2.8. Thanks for inspiration. Cleaned out my garage to park it in tomorrow to clean this out.

I have owned my 99 Z3 for 20 years The best product that I have found to clean the back window is called acrylic werks polish It's kind of expensive $25 but works the best has to be applied with a damp microfiber cloth

Hi Mark, been meaning to respond. I had good luck prior to your video with Meguiars Clear Plastic Cleaner #17 then per instructions apply Meguiars Clear Plastic Polish #10. My results were pretty dramatic as were yours. I also have a bottle of Meguiars Clear Plastic Detailer #18 that is meant as a daily / regular maintenance cleaner. These are all new to me as recommended by the previous owner for this convertible top. A final note: for my all my of car's plastic headlights I have been using Meguiars Plastic-X as far back as my 2013 Dodge Dart. They all look as-new to this day. Enjoy your channel!

Great Job.

Love you'r video from Alloa scotland

I used plexus yesterday. Really satisfied. I see why you didn’t video cleaning the inside surface. I think most of the yellowing was on the inside. I can see clearly. 👍👍

You put out the best Z3 videos, Moment of Zed. Have you had any camshaft position sensor problems?

I live in Arizona have a 2001 Z3. I found that the scratching can't be avoided unless you change the felt pad that it sits on When it is Down. I found out the hard way that this needs to be replaced after I put in a new top and it scratched right away.

I just got my first car, z3 with 79k miles🤗

*Update to ebay soft top. The quality was great for the price ($165 shipped), and got a local shop to install it for $180 and they took about 4 hours to fit it. So if anyone is weary about replacing the entire top because its old or you just want a different color, ebay z3 soft tops are a-okay.

Any recommendations for a cheap plastic window replacement? Someone cut my rear window while my vehicle was parked overnight..

if its scratched you have to buff out it out with a polish. Also, I put an old towel over the window when I take the roof down to avoid the roof and bars scratching it in the first place.

next time use lemon pledge :)

i can barely see thru my rear plastic ;)
