The guy who does all my paint and body work uses 3M body panel sealer to bond cracks in any of the Mercury ABS type plastics I bring for him to repair or paint.
I'm sure there are cheaper brands out there , but that's what he uses .
He scuffs the parts pretty deep with 36 grit to get a good bite . Lot of finish sanding and body work to make it look right .

Need the gun and mixing tube as well ....

There are cheaper, but nothing compares to 3M panelbond. It's the only product in it's class.
