Glue, Epoxy, Weld? Plastic repair...

What do you use and what would you do to fix this?









I realize JB weld is certainly not the best, but it does the job. And others have had luck with it. Then there is Devcon Plastic welder, another 2 part. I'm waiting on a test piece to dry with it, so far, the results are...ehhh

Then I've read up on Plastex plastic repair, where they use a plastic powder and a liquid which seems to chemically, not mechanically, bond the plastic.

PLASTEX PLASTIC REPAIR KITS

So I'm waiting for a small $30 kit to arrive from Reno, to give that a try.

I have not tried to actually weld plastic though, with a device similar to a soldering iron, and using a like material, perhaps some pieces from a junk fairing.

I've also heard of guys cutting small fairing pieces and melting them with acetone, or pipe cement from Home Depot. (Oatey brand.) and letting that melt over a couple days, and spread that over aluminum or fiberglass mesh...

SO, with that said, what have you guys had luck with in the past.
