Cleaning the rear plastic window

[dlq04]

Dave, we were chatting about what a pain it is. Afterwards, I decided to try something. It worked great. I posted the details here.

Very nice. I guess it's true what they say about necessity being the mother of invention. All this talk about cleaning the plastic rear window has guilted me into doing it again on mine. It's 8 years old now but the tint has certainly kept the UV rays from yellowing the plastic.


I have also discovered that it's not necessary to replace the cling tint every year. In the spring, after I remove my hardtop and put up the soft top, I can see that some of the edges have puffed up and air and dirt has infiltrated under portions of the tint. I then peel it back just beyond the bubble and wash the window and the underside of the tint with Windex. Then I spray an alcohol/water mix (1:10 ratio) onto the exposed areas and squeegie it back down. This makes it good for another year.

I've never experienced the yellowing associated with my old British motor cars. :) However, my top has been down for 99% of the 41,000 miles.... so that could be a factor. But it does definitely get cloudy and this method took care of that.

I've seen this on an S2000 (not mine) and I've got it happening on my 3M film on the front bumper. The only way I could actually tell it was yellowing is that I a new bumper and put on new film. Next to each other, you can tell the old stuff is slightly yellow.

Novus # 2 is what I use for all plastic. Works great on rear window and headlight covers. Even when there are deep scratches I use Novus # 3 and then # 2.

I haven't seen the 3M subject discussed in years but as you no doubt recall it was a 'hot' topic in the first couple model years. I always suspected it would eventually yellow but since no one, not even the sellers, could say what the long term effects would be I chose not to try it. I have only have a couple stone chips which is amazing considering how crappy MI roads are.
