Has anybody ever successfully glued 2 pieces of silver mylar parachute material together to make a bigger chute and had it stay together during deployment?

research indicates to me that contact cement( roll or spray) might work. Heat sealing ?

I found this:

"it is possible to glue together multiple sheets to form a large sheet. To do this, use the type of contact cement that is used for styrofoam. It does not melt mylar and it dries quickly without the remaining exposed bits of cement still remaining tacky."

to which contact cement are they referring to?

UHU POR ? Weldwood?



TIA
