Repairing leaking canvas seams

[BobMcBob]

The canvas roof on my campervan has begun to leak, there's a single very obvious point where water is finding its way through one of the seams. Anyone have any ideas on how to seal seams on canvas?

Many thanks, a useful resource. I've been recommended to use 'McNett Seam Grip' so we'll see how I get on.
