I've got a bad water leak coming from the windscreen on my VW Type 2 Camper that will ruin anything else I'm trying to fix on the van unless it's resolved. And it just won't stop raining!

I've already bought a new windscreen seal, but before I risk taking the screen out and breaking it and the expense of paying someone to do that I thought I'd try Captain Tolley's Creeping Crack Cure, a water based sealant which seems to be very well regarded in marine circles to see if I can fix it cheaply myself.

Will it work? Watch to find out!
