Can you use acrylic high build weld on that. My memory is kind of fuzzy.

I've spent hundreds of hrs. welding PVC, a few welding polyethylene, but never p-propylene. If you find the answer please post it here. I had to figure out how to do what I did. No real instruction or manuals available to me. Experience showed me what temp to use and what rod to use for the polyethylene.

I'd suggest looking up some product suppliers and calling them.

I welded the fairing of a 1000 GSXR. I'm not sure what it was made of. I'm fuzzy on the details but was told if you cut off a sliver of it and put it in a glass of water it would either sink or float. Again I'm fuzzy but if it sunk it could be welded, if it floated it couldn't...or visa versa. Something like that any way.

Didn't the magazine run an article on plastic welding some time ago?

PP is weldable but not as good a candidate as the amorphous materials like PC...

My brother bought a wrecked Moto Guzzi whose fairing is made of Polypropylene. It's not ABS, which is apparently the fairing material of choice by the Japanese mfgs. He's having trouble finding someone who can weld it, and he lives in SoCal. Anyone?

I have glued and filled motorcycle plastic with a paste made of super glue and baking soda

I've only done it with ABS plastic using a soldering iron and some zip ties as filler rod....

That's what I've done. However, I know my brother has a specific gun at work for bumper repairs. Wonder if its similar.

In reply to escort1991:

Probably is, you heat the two sides of the crack up just enough to become sticky, then melt the filler rod inbetween. I need to redo the tail on my '04, but that was my fault for having a passenger on a fragile to begin with tail.
