A little while back I did a little trip and fall while carrying my D500 and 200-500 lens. The only casualty was my lens shade which was cracked. Being as retail on a new one is $53.00 (pretty crazy for a piece of plastic) I attempted to repair it. I've tried both epoxy and Tamiya cement. Neither worked. Any adhesive chemists out there? I really don't care what the repair looks like as it'll be covered with a camo Lens Coat. Thanks in advance.

How about tape, then spray the hood flat black?
The problem is, there is too little surface area on the broken edges of thin plastic, so you will have to another piece of thin plastic, metal, or heavy cloth tape on top of or around the crack, If you are not concerned about the cosmetics, you can cut a patch out of plastic or metal shim material. Gorilla glue and tape can be used to hold everything together. Try to clamp it in place overnight. There are some adhesive products made by Flex Tape that is also very strong.
You can coat the outside of the shade with any finish, but if you need to paint the inside of the shade, use flat black lacquer.
There are some plastics that seem to resist adhesives. I find that if I rough up the surface, the Gorilla Glue will work on just about anything. Apply it sparingly because it tends to expand and leak out of the edges. If it gets on anything or any place where you don't want it, clean it off immediately.
An acetone base glue?
Stuff they use for plexiglass, it melts (welds) plastic.

Lens hoods are more than likely thermal plastic and Acetone will not touch them ( eat or melt).
Super Glue will hold for a while. My suggestion would be to drill small holes on both sides of the break then use JB Weld on BOTH sides making sure it runs thru the holes, not pretty but it will work, I repaired a broken fan shroud mounting boss on a 6.9 Ford diesel and the last I heard 4 yrs later it was still holding.The reason for this repair was at the time the Bus was so new it was going to take almost 30 days to get a new shroud and that would mean lost revenue, in fact the day after the repair the bus left on a 2 week tour earning over 3K.

I used crazy glue, fixed it right up.

I used this on my hood and good as new.
I have used BONDIC UV glue on several things around the house great stuff. It's a UV cured glue. Not cheap but handy. The kit I got was $35 from Amazon, it came with 3 containers of glue and the UV light.
Super glue and baking soda. Google it.

JB Weld will do. Simple and not expensive.

I've tried to repair some plastic an that JB weld is good. I agree with the little holes. I've used boat epoxy too.
I tried to repair my kayak and that plastic is tough to repair. If it's same plastic good luck. I saw people use parts of a home depot bucket and heat them together but you might unround the hood so be careful
