I think the only way plastic welding can work is to find a donor piece of the same or knowing exactly what kind you have. PW has my interest but not enough to give up fiber glassing & the use of epoxies & like mentioned reinforcing with metal. Keep us posted on what you do.

The shield says ABS on it and the rod I used was ABS. I was able to mix the rod with the original plastic, but some of it seems to have burned( I'm not sure if it's the rod or both plastics). The instruction book that came with my welder, mentions only one kind of plastic that would turn slightly brown, and it wasn't ABS. It's hard to tell for sure if it's brittle, because I did such a small spot. When I tried to twist it, I thought it made some small popping sounds. Maybe it wasn't the weld. I think it may have air pockets too. The videos on the manufactures website make it look so easy. I would like to make a really good fix.

Before I get all down about this(not that I should get down about it, it's only plastic), I have had some good success with a product called Plastaid. I used it to make a replacement tab on our JD LT155 lawn tractor and it's been going for 2 years or more and hasn't broke.

I looked in my plastic welding book and going by the recycling symbol on the hood pieces, they are either ABS mixed with another plastic, or not ABS at all. This is probably why it did not weld right, I was using the wrong welding rod.

If that does not work , I have used a 3M product in the past called Structural Adhesive
its similar to a 2 part epoxy system, but a lot stronger, I have used on fiberglass, and plastic applications with good results.
