Thanks Gord I’ll have a look.  The tent has a ton of little holes - almost like it’s deteriorating so I’ll need a fair bit of the stuff.  Thanks for the suggestion.

Gorilla Clear tape can be good for some jobs. I've used it for a long-term seam repair on a folding skin-on-frame kayak at waterline where hypalon rubber meets the canvas deck. I was surprised at how well it adhered. That repair job, however, hasn't been given a follow-up testing in wet and rough conditions. Tear-Aid is in another category altogether, i.e. much more expensive per inch of tape. I've used it for long-term repairs on awnings, tents, bug netting, canvas, and nylon clothing. It behaves a lot like Tenacious Tape. I like it a lot and usually carry some in my repair kit. There are two kinds: one for vinyl and one for just about everything else.
