T350 windscreen going white

[valhalla]

Anyone else had this yet? my T350c seems to have got the "white around the edges" syndrome.
I have seen lots of Tivs with this problem, but not one this new (2 years).

Yep mine went this way Dave, I had it replaced, but only because I had a horrible stone chip

My mate's had a similar problem with his Tam's rear screen. He's now using a product that restores the plastic, and apparently it makes quite a spectacular difference. There's a thread about it somewhere on this site. Its called 'Renovo'.

Renovo is great, used it on my old Chimaera in the past.

The front screen problem is delamination. This is when water gets between the layers of the screen itself. Which means water is getting into the screen seal. You might be able to minimize the worsening of the problem by resealing around the screen rubber (rubber seal to screen, not rubber seal to car).

I had my screen replaced after it got badly scratched while at the dealer or bodyshop. They replaced it FOC, but it is a very tricky job to do without causing any damage. I got a nice stonechip in the line of sight a few hundred miles later - typical.

When I had this on the Cerb I was told it was due to poor manufacture of the screen itself. It was bad enough for them to reject 3 supplied screen (because they would have done the same thing).

Obviously being exposed to water will highlight the problem, but you should be able to leave the windscreen in a bath of water and it never delaminate like that (or so I'm told).

This is a problem common to many fibre-glass cars, including all TVR models. Water does not cause the delamination, it merely shows up delamination where it is present by creating the milky appearance. Basically laminated screens are a layer of glass between two layers of plastic. TVR screens are bonded in place, with the bond between the bodywork and the plastic laminate. The bodywork of a fibre glass car flexes, glass does not flex much, so you find that the stiffest part of the body is the windscreen. As the windscreen is trying to resist the flexing of the bodywork, the plastic laminate holding glass to fibre-glass, eventually parts company with the glass. There does not appear to be an easy solution other than to live with the milky edges, or change the screen every couple of years.
