HELP: Wetsuit repair

Just packing my wetsuit for weekend race and notice a 2 inch (!) tear on the underarm section.
It’s an IM Stealth suit and looks to have come apart at the seam and then torn. I need to do a quick repair for the race but have only done small nicks…
anyone any idea on how to repair such a large hole?
If it wasn’t so close, I’d send the thing to IM for the repair…maybe after the race I’ll get them to do it properly…

Order some of this:
Aquaseal

We can get it to you overnight if needed!

Thanks. I actually have some AquaSeal…will that repair such a large tear?

Duct tape for a quick fix…

I would duct tape the split together, and then slather it with Aquaseal. Not an ideal fix, but it will work!
