I need like an 5 or 8 hr way to glue plastic together, and it will stay solid, something like JB weld but a quicker dry.
touch cement. word glue to the two surfaces and permit dry (approximately 2 minutes) then press jointly. i could advise you attempt a pattern section to make valuable the chemical compounds interior the glue won't injury the factors.
Have a specialist plastic welder to weld it up for you as it's stronger than most glues today besides most plastics don't glue very well anyway! Most 4wheeled motor bikes have plastic flaring guards can quite successfully be plastic welded, same as most modern cars with plastic bumpers or fenders as the yanks term them. Your best bet is to have your plastic welded it won't cost you the earth! Cheers!
