(wildcat) drybag seam repair

[Al]

The seam tape is coming off my wildcat drybag.

What have people used to retape seams on thin fabric - I'm wary of melting it if hot taping with an iron

Thanks

I've done an entire tent with McNett seam sealer (the stuff in a tube), mixed with a little bit of white spirit until it is just thin enough to put on with a brush
