Plastic Welding the Firebird Bumper...Again!

A while ago I tried to fix the bumper on the Firebird with a plastic welding method using hot staples and...well...it didn't really work all that well. So trying a different method this time with what amounts to basically a soldering iron with a special tip, and some plastic stock to melt to it.
Never done this before. No idea if it works.
Side Note: Definitely should NOT quit my day job and start fixing bumpers.

Good Stuff Ryan. I use this same iron to fix my rubbermaid water troughs. Only things with those is i need special filler that is poly eurethane. You think that plastic filler you have is bad that poly eurethane is really bad. Definitely a mask worthy job.

Also if you know the type of plastic the bumper is you can get the filler plastic the same so it bonds.

I'll check it out. Still says it's used for rigid and semi-rigid plastics. I wouldn't say this is remotely rigid.

Someone said that only works on hard plastic as well. Are there different kinds? Shoot me a link if you know of one. I'd love to give it a try.
