I've got a leak. A tiny one and it only happens if the van is parked in a certain way.
I've got a massive 800x500 roof light and sometimes the water drops down the winding handle.
I've been up there, removed the roof light and plastered as much silicone, 007, sticks like shit etc but I'm still not catching it.
So I wondered if it would be possible to fibre glass the area around the roof light?
Is it easy to do and does it add a lot of weight to the roof? The roof is already drooping a little and I really don't want to add any more weight to it but I really would like to stop the leak.
Any ideas on fibre glass or an alternative?
