I am going to try it this weekend. I only found out about the zipper last week. I found it, and unzipped it, but didnt have time to clean the window. I will let you guys know how it goes.

 

There was another thread where it was advised NOT to unzip the rear window.

 

Actually... i think that thread may have been started by me... I was asking if anyone knew how to unzip the rear window and that we sparked a big arguement to whether it is ok to even unzip it at all.

Personally, I feel that if you only do it once in a while when your window gets super dirty, it won't be a problem.

I unzipped it and cleaned the inside of my window this weekend, and here were my impressions:

1) Cleaning the inside of the window w/out having to do contort my arms into uncomfortable positions makes it so much easier.

2) The window does NOT flap completely over, so its still a bit of a challenge on how to get some good elbow grease back there.

3) Being able to put one hand on the outter side for pressure, and polish with the other hand on the inner side does help with buffing out those minor scratches.

4) Zipping and unzipping is very easy, and the zipper WILL NOT fall of the teeth... I saw that mine had metal staples to keep the zipper from coming all the way off.

Overall, I think its worth it to get a good polish in once in a while. I will let you guys know if my car starts leaking from that area... but i doubt it... there is a canvas flap that overlaps the zipper by approx. 3 inches.

Hope this helps!

 

My initial thoughts were that unzipping the rear window would make it easier to clean and polish the rear window, but other people said that it wasn't meant to be unzipped except when replacing the rear window. I've never heard of a "one-time use" zipper and I've had no problems zipping and unzipping the zippers on my jackets, coats, pants, backpack, etc.

Could you see any reason that you shouldn't unzip the rear window?

 

It zipped up and down really easily, and the velco pieces are just as sticky as before. There is a rubber strip underneath the outside of the flap that you will need to fold back in place... but I dont think that it will matter if you dont b/c the flap covers the zipper seam by 3 inches... i dont think it will leak at all.

So really.. I have no idea why it is a bad idea to unzip it. But taking others' advice, I will still try to only unzip when my window gets super dirty

 

I'm surprised no-one has mentioned Hindsight for plastic rear screens, plastic lenses etc - this was invented by a Scottish surgeon and is used by the Britsh army to polish the clear lenses on their tanks apparently...

I bought some from www.morethanpolish.com for my mother in laws Z3, which had an awful bar on it plus loads of scratches, milky fog etc - the lot, and its amazing. I've since spoken to several MX-5 / Miata owners who also have used it and tell me it lasts for ages, makes the screen more supple and is the answer to their prayers.

I think they'll ship to the US - their site doesn't say otherwise.

I know its not cheap but you get what you pay for, and I'd hate having to repeat this job (yes, I had to put it on !!)

 

Thanks for the tip. I'll have to give it a try.

 

I've been a user of Plexus for some time now, but recently the window has gotten pretty foggy.

I decided to try another product (meguire's PlastX). Man this stuff works wonders!

It is clean as glass now and so much easier to apply. You just wipe it on like wax and use another microfiber towel to take it off. Simple. Took me about 15 mins and now the plastic rear window looks brand new.

I tossed the can of Plexus.

 

i have a question on my rear window, it is really wavy, it has a lot dips in, in several spotsand . i was wondering if anyone knows a way to make it tighter, or how to get rid of this! it bugs the heck out of me as it makes my window look that much cheaper! thanks in advanced

 

As mentioned earlier in the thread, you should try the hot water trick to remove waves and dimples.

I'm getting ready to bust out my new PC on both the window and the headlights. I've got the Meguiar's 10 and 17, which have a # to call on them, so I guess I'll consult with them on the best PC speed and pad to use.

I feel confident in using the PC, as I've given it a thorough workout on my brother's beat-up 91 Accord and even at top speed with an orange (cutting) pad and some fine-cut compounding liquid, I wasn't able to (further) damage his paint or eat through the clearcoat.
