Roof down without creasing rear window?
Discussion
I know this might sound strange, but since buying the Griff I've had the roof off 90% of the time, but always just the targa panel. I've never dropped the rear section because of the creasing to the plastic rear window.
Is there a knack to folding the rear section down without putting creases in the plastic? I've heard about using a rolled up towel, but that's crap (i'm not carrying a towel around with me like Rocky Balboa)
Thanks in advance for the answer to the noob question.

Best to drop it only when its warm (above 15 degrees say) as it is not as flexible when cold and more likely to crack. Also worth treating it with 303 (you can get this from The Poloishing Company) as it makes it more supple and it gives UV protection.
You also need to release the velcro on either side before dropping the "mullet".
Draught excluders work well.

To reduce the stress on the rear window, I am always careful to push the plastic window section behind the seatbelt top mounts...after releasing the Velcro. As I fold the window section, I make sure I have a single "soft" fold across the plastic and have never had a problem. It is always worth checking the window is clean before folding, as I guess a small amount of dust and dirt can cause damage. I also occasionally use the Renovo plastic window polish...time consuming but worth the effort. Hope this helps?

+1I'm very impressed by that stuff; the screen they use to demo it on feels more like it's made of soft silicon.....

Makes the window very supple, even in winter.
I’ve had Sportscars in the past with a zip around three sides of the back window.
The window sown in at the bottom like standard, but the zip runs up one side, across the top and down the other side.
When you want to fold the hood down, you undo the zip and it the window goes inwards, lying flat(ish) over the rear parcel shelf.
You can also drive with it open and the hood up.
These hoods have an overlap around the window. This means you can’t see the zip and any rainwater is carried past the zip instead of soaking through it. That means the roof has to be made as a zipped rear window form scratch.
I’m intending to ask Dave Hammerton if he can do me one that way when mine needs replacement.
Has anyone else tried this on a Griff?

That type of window is on the MGF uncle fester and I absolutely hated it when I drove Mrs B's 'F'
You needed to be a contortionist to reach the zip and pull it around the window. I used to have to kneel on the drivers seat to do it.
Might be better on the Griff as the seats and high parcel shelf aren't an issue for us though.
Try a dry run test before you do it.
Another vote here for 303 sunscreen for plastic windows too

Yes, my TR6 had this window type too. And it is was/is much better. I had also thought about getting it on the griff.The window sown in at the bottom like standard, but the zip runs up one side, across the top and down the other side.

The MX-5 had it too, it worked well on that. Your problems probably say more about the MGF than the actual concept You needed to be a contortionist to reach the zip and pull it around the window. I used to have to kneel on the drivers seat to do it.

Mine has a zip fitted as per discussion.
I was fitted by the previous owner, who had previously had a TR6 and MGB.
As described there is an outer shroud that covers the zip on the outside.
I must say I don't use it nor particularly like it:
- The outer shroud in my opinion spoils the line of the hood when it is on
- I find that when unzipped, as the screen is wider than the gap between the stays so you still have to role / fold the screen (I think TVR's are unusual for soft tops as they have quite a wide screen which is part of the problem)
Will post a couple of pictures later
