Ok here is the update. The test was a success! If you do not mind losing a mirror 😊. After I got back up and running, I also changed filament, I changed to 3Dxtech CarbonX™ NYLON PA6+CF. This filament prints very well by the way.
So, to recap, I used standard 12" X 12" mirror tiles from Home Depot. I particle blasted the mirror to get it some texture then added two layers of Nano Polymer Adhesive letting it dry between layers. I did not use a brim this time with the added texture from blasting the glass it was not nessary. Enclosure temp was around 82⁰C Extruder 275⁰C Bed was 110⁰C. I started to print last Thursday and printed thru the night until Friday then shut everything down around 10:30am with about four hours left to go in the print. I came back in on Monday morning and restarted the print it finished without to may problems.
First issue there is a small visible line where the print restarted but I could clean this up if I wanted. This restart line did not affect the strength of the part at all. I dare you to try to break this part! Next, The part was stuck to the mirror so well that it broke trying to remove the print. It also left small pieces of glass stuck to the bottom of the print. I removed these with a small die grinder and proper PPE of course.

You can see the re start line at around 62mm in the photo.

This is the finished part.
I think I will keep trying but will cut back on the adhesive. Thanks for all your help and have a great day.
