A slightly strange development. A week after the sealing kit was fitted, the leak in my bonnet seems to have dramatically decreased.
Shortly after it was fitted, water was still pouring out of the back into the engine bay. Since then, a week of dry weather so no
problem. I washed it yesterday then opened the bonnet to clear the water away only to find that very little water came out, a few drops from the back and a tiny trickle at either end (but that goes into the drain channel which is okay). To double check it, I poured about 3 pints of water over the bonnet strip, dried the bonnet then opened it. Again, very little water came out, most of it at either end of the strip.
Nothing has been done to it, except that the car has been used all week, is it possible that the heat from the engine is having an effect on the sealing kit (there was no mention of this in the instructions SEAT issued). When the kit was fitted, I only had a 5 mile drive home and it poured down on the way home.
John (Datapro0). How many miles did you drive before opening your bonnet to check it? (sorry, I can't PM yet)
