What da heck is with this plastic??

A "Space Age Polymer"?

Hi John, just a thought-did you scrap off the paint in the area to be glued? I was convinced to try JB Weld by gunrunnerjohn, to repair a part on my Aristocraft diesel, and it worked well.

Let us know what worked!

There was no paint on it Artie, and I did scuff up the areas to be glued first.  My next step was going to try a primer paint on it before gluing.

Delrin probably - tough to attach anything to it.  Some limited luck using Goo on it and CA on the other component.

I've run into similar situations and it is very frustrating when nothing sticks!

Maybe it needs to be "heat" welded, which would be a pain and possibly distort the delicate fence.   

I've used Dupli-color CP199 Clear Adhesion Promoter Primer with excellent results.   I found it in the auto parts stores and I believe it was available on your favorite internet  mail order sites.

It comes in a spray can .  I spray a little in a small metal container and apply with a swab.   

It softens the surface ofplastic and leaves a CLEAR primer surface.  I never had any type of plastic that it didn't work on in auto ,motorcycle and household projects.

Read instructions on the can  for best results.   

Could very well be Delrin, mwb.

Dallas, C199 sounds like a product I should have on hand to use the way you do. Thanks for the tip

If it is delrin, a scuffed/gouged up glueing surface that has been thoroughly cleaned with alcohol after scuffing, and a strong epoxy such as scotchweld works well.  I do this all the time for my day job.
