I have a cracked headlight motor cover I want to repair. What type of plastic are they made of so I can get the correct type of cement for a permanent repair? (IMG:style_emoticons/default/confused24.gif) Thanks

I would guess polystyrene, or possibly ABS (Acrylonitrile Butadiene Styrene).
Maybe get an old broken one and experiment on it first. |

Figure out who your 3M rep is in your city. They make all kinds of glues and can recommend the best thing for you and tell you where to buy it

The hobby store will have glue that works on both styrene and abs, assuming Jeff is right... (IMG:style_emoticons/default/beer.gif)
Most of the injected stuff is abs. |

ABS is the common black plastic plumbing pipe, ABS 'cement' would work well. Its really a solvent not an adhesive.
Model car kits are styrene, so model cement should work. I am sure there are others glues/adhesives/solvents that would work, why I suggested experimenting on a broken one. |

"Styrene and ABS Plastic Solvent Cement"
ABS = "Acrylonitrile butadiene styrene" Further proof that the are styrene. What am I not understanding fro your post? |
