Another day, another damp van!
This one was a Seitz cassette window that is letting in water. The water ingress can be clearly seen as black, mouldy wood. The window is sealed by a rubber gasket on the inside return of the external part of the frame and then an internal frame is clamped using a dozen or so screws through to the external section with caps over.
As a repair, most people just run silicone around the outside of the frame to the body..... Silicone - pht! The stuff should be band! This will last for a few weeks - if you're lucky - then capillary action will result in more water being drawn in than was leaking in before!
The damaged gasket should be replaced and the window refitted, but we don't do it that way - the gasket's failed once, so it will again. We rip the gasket off, run a bead of polymer MS bonder (we use Soudal Fix-All - available in our shop) in the resulting groove and refit the window - ensuring an even spread of excess sealant on all edges.
The excess is then scraped off and the edges 'washed in' with a special solvent (a specific branded Panel-Wipe that doesn't react with the bonder).
The result is a very neat finish that guarantees no further leaks as the bonder will out-live the van!
Well that's one less joint that water can now leak through - Job Done!
