Plastic Repair

I just bought a used door panel to replace the one on my Blazer, which looks like new, except that where two screws attach it under the door handle to the door, the plastic is broke out. It had been attached using a couple of flat washers to fill the gap, which I could do also, but I would like to restore it as close as possible to new condition...or perhaps stronger, since these panels damage easily.

Therefore, I'm considering using or making a couple of thick plastic "washers" and gluing or welding them in place. I've read some about gluing other types of plastic, but the best that I can determine, these are made of molded ABS...at least they were a few years earlier. What is the best means of performing this type of repair? Appearance is not really important, because the repair will not be in a visible location.

It is curious, because while Googling on this, I've found numerous answers, from epoxy, acetone to glues designed for ABS plumbing pipe. As I said, the important part for me is the strength of the bond. Appearance, drying time, etc. are not an issue, I just want to fix it as permanently as possible.

Duct tape to the backside to keep it from spreading then use the above suggestions with resin. IMHO
But what do I know.......If it is broke use duct tape to fix it. If you want to break it use a big hammer.

That sounds akin to my brother's view of repairs...if it doesn't work, get a bigger hammer.

They make a product, I don't know if you can find it in your area, but it's called "Plastic Weld", it's 2 tubes that you mix like epoxy but it's for plastic. I got it at the local auto parts store. When it's dry it feels like & looks like black plastic.

I have seen some ads for this online, but the thing that bothers me is the word "plastic", because there are so many different kinds of plastic. The fact that they don't bother to list specific materials for application is what bothers me.

Seek,
Have you a local body shop or custom shop you can visit and pick their brains on what they use?
That's where I would start before going out and buying something that may or may not work.

Reasonable advice, except that my experience with professionals has not always been so good. The only way to know how good their advice is to either have used them enough to have gained confidence, or simply take it on blind faith.
