Griff windscreen sealant
Discussion
Hi all,
Rubber deal has come away from the griff's screen along the top. I have some black sikaflex 291 at the ready but don't know how to get the old sealant off from around the top of screen - see pics. Any suggestions greatly appreciated and also any tips on how to get a decent quality finish.
Cheers, Stuart

A sharp scraper and/or razor blade will do the job. Once you get a start it will often pull off in chunks. Obviously be careful you don't scratch the glass.
Silaflex sticks to anything and everything so don't apply too much or it will go everywhere. Wear gloves and make sure that everything is clean and dust free. When you've applied the stuff clean off excess with a cloth and a razor blade. It's also probably a good idea to tape the seal down in position and/or put your roof panel back in to ensure the strip is located both tightly and in the right place.
Make sure you don't get Sikaflex on the canvas of the panel.

Razor blade to get rid of most of it, then a good rub down with white spirit will see the rest off.
As Im sure you know sikaflex is messy stuff. When I have done it in the past I mask up both edges . Put on gloves. In fact put on 2 pairs. Then run a bead of it between the masked areas, then I run a finger around the seal to flatten it.

Given that all automotive grade urethanes require both contact surfaces to be 'activated', introducing an oil-based product is not a great idea if you want the fix to last. The substrate should be free of such contaminants if you are to achieve a lasting bond.
Good point Glassman - I defer to the expert on this one listen to him not me !
I would normally give it a wash down with diluted washing up liquid to remove the final residue after the white spirit then a good rinse with water but I suspect this would still leave something behind.
I wonder if some kind of alcohol rub would be better to prep the surface and remove the last traces ?

I'm sure that modern automotive products do require the prep that glassman suggests but Sikaflex does not, it just needs a clean dry surface, so yes the alcohol would work as a cleaner.
I wonder if modern materials are appropriate on a TVR as the fibreglass flexes? If the modern materials set hard or harder than Sikaflex and the screen is then held rigidly the screen will crack.
Just a thought?

I've just done mine.
Cleaned it with a blade then used thinners to get off any residue.
Washed and dried.
On the advice of a guy who fits classic windscreens I used kitchen sealant to bond it. In his opinion it is as flexible and not as 'Bloody Sodding difficult' to get off in the future.
But then I used a Dyson hose to get my ventilation working....
