Hi, what is your opinion of me taking my windscreen out and re sealing it,
without breaking it.

It looks horrible where the origenal sealant has failed and sucked water in,
leaving white water marks.

Do some research & use a fitter who has been doing this specific type of work & not a generic insurance type fitter.
Might be worth having a chat with you local specialist paint place & ask who they use.
The chap I use has never let me down, never broken a 'screen & never damaged a finisher trim (he charges £55 p/h though - pays your money, takes your choice), bear in mind that all glass comes out on pretty much everything we do here!

Cheers motive, did do a search with a little luck, was thinking of doing it myself,
bit skint at the moment.

Phillpot, i think the black edging, where the watermarks are will scrape
off, then can repaint.

1. If you're asking... none/zero/forget it

2. The 'seal' can be tidied in-situ; you can even paint over the the de-lamination pockets of air you can see... but... to tak ethe screen out for these reasons, you might as well renew the glass.

OK cheers glassman, think when i got spare cash will try it anyway,
if it breaks, i'll get a replacement.

I think painting over would'nt look as good as painting the back/inside.

The main reason for my posting was, i think the finished sealant aroud the screen is not the eye candy it should be (no disrespect to the tvr employees that done it).

I started going over the valley between the glass and the paintwork, with black sealant, done about 10" looks really good, but your eye just looks
at the air pockets behind the glass. See pic below

the marks on the glass look to me like de-lamination ( as mentioned by glassman)
IMO this cannot be cured only hidden, moisture is seperating the layers of glass from the plastic section in between.
on such a nice car it would be a shame for a stone to bounce up and crack the screen.

THe bubbles are caused by the sealant attacking the laminate layer in the glass. Make sure you use the correct type if sealant when you replace it otherwise it will just go again. Don't use silicon sealant that you get form your local DIY store.

Ah glassman, i think i got it now, the problem is inbetween the two
pieces of glass, so the only way to make it look better is paint over
it, or buy a new screen.

Monster, what is the correct sealant. what if i just want to fill in the
gap/valley between the paint and the glass, like my second pic shows.

Cheers for the replies, you learn something new everyday, on these forums.

You need to find one without acetate in the mixture as this is what attacks the interlayer. You should be OK with Low Modulus sealant. The stuff with acetate in smells vinegary and is high modulus. Can't recommend a particular brand of the top of my head.

I use Sika (automotive lines) which, in my opinion is the leading brand. But there are other brands which are very well suited, such as Dow Automotive and Eftec's Dynol and Dynatrol range.

FWI: there are sealants for bathrooms and sealants for indirectly glazed vehicles and other remedial work. But for bonding windscreens and filling gaps (like in the case of ths S2 - and without crumbling at the slightest bit of torsion / pressure from a water hose) Polyrethane adhesive is what you need.
