Hi guys,
I'm going to weld my underbody cover for my engine and want to know what type of plastic welding rods I need to do the job. Is it possible to take one piece of the underbody cover and use it as a welding rod? because I have plenty of spare underbody covers.

I also want to know what type of welding plastic rods I need to weld Repair the back bumper. If anybody can help me out with this it would be greatly appreciated.

 

Usually the symbol or letters for the type of plastic will be cast somewhere on the part. It might be easier and stronger to bond & rivet/bolt thin aluminum sheet metal to the damaged area rather than weld it since that material is thin. I suppose it depends where and how extensive the damage is.

 

Yea, I bought a rivet gun from Harbor freight. It sucked. My damage isn't that extensive and really only needs preventative maintenance. This is like my 3rd btw. So I need the maintenance.

The only markings I have found on the plastics are these:





I haven't been able to find any info on the three lines and so am thinking about trying a plastic specific epoxy, if I cant figure the plastic type out.

 

Most of the black fender liners and such are ABS...

 

thanks for the reply but how do you know? I think I've done a thorough google search and cant find any exact info. Leaves me guessing, which I dont like to do.
