Does JB weld only work with metal to metal projects, or does it work on metal to plastic/polymer jobs too?

It works with everything. It's a epoxy. Just make sure to remove any oils before applying.

I love that stuff.

Thanks ZW17.

There are a number of 'plastics' than even epoxy will not bond to reliably.
Teflon is one, some polyethylenes are another.

I would hope that would be obvious.

JB Weld is great stuff. Especially when squirt into car door locks. Don't ask me how I know this.

Now now, keep it legal.

your chances of getting a good bond increase dramatically if you can (a) get rid of all oils, and (b) scuff up both mating surfaces.

I've worked with the stuff and I'm wondering how you "squirt" it into anything. It's thick once you get the two parts mixing. Go over the squirt technique for me if you can.

ahh good ole jb weld.... as a joke i bought my buddy some super sized industrial tubes of the stuff for his bday. lets just say he had it all used up within a few weeks. used it to patch up some leakes on his plumbing. lol... damn redneck!

but to answer your question i dont know how you would squirt it into any area. you would have to slowly jam it into the area using a small piece of metal, plastic, etc.

There are much better epoxies for thin cracks.
West Systems makes a good line.
Without thickeners added epoxy is surprisingly thin (and West has thickeners all the way to past if needed).
