I think I found a solution until they come up with a good stuff. There is a 1" 3M double side tape strong as hell. I will just have to cut 1" strips of Ripstop and stick it after, more work but better result.
place the 1" wide 3M tape strips next to each other to make a 6 inch wide repair patch.
I've done this, then broke out the sewing machine a month later, & it was still good !
It's Lighter if Ya only use the 1/4" wide 3M stuff, and only place it where it needs sewing.
A "Lot" lighter !!!
Also -- always try to wipe the repair aria with denatured or 91% rubbing alcohol , prior
to placing a patch.
