Repairing Cargo Box

[architect]

What's the best way to repair this cargo box damage? This was being tossed by relatives but figure I could try to repair and get more life out of it for myself.

I have some epoxies that might work against some temporary substrate?

Difficult to tell in the photo but below the right hole is a big chip that would enlarge the whole significantly.

Plastic welding kit perchance?

rivet a piece of something in from the backside and fill the big voids up with black urethane caulking?

I’ve always wanted to try plastic welding.

Failing that, maybe pop rivet + reinforcements inside and bond/weatherseal. Might try some of the adhesives used in the autobody trade?

It’s probably High Molecular Weight PolyEthylene (HMWPE, not HDPE). HMWPE doesn’t really bond well but does thermoform quite well.

Interested to hear how it works out.

Edit:

It might be ABS, in that case it will solvent bond quite well. Try a little ABS adhesive on a hidden surface to see if it softens the material. If it is then get a bit of scrap ABS sheet and patch away. Overlap the holes by a half inch or so at least. Clamp the patches until the bond has cured.

Soldering gun or a pencil torch & some black zip ties as filler for something cheap to try.

Or some epoxy & paint.

My vote is bondo plastic filler over a mechanical repair..sheet metal and pop rivets. Thin coats, a bit of sanding, semi gloss black spray after
