Cross posted to decorative painting forum I scored a couple of beautiful pendant lights at a Recycle Store for a very good price (turns out they are still for sale and at a pretty penny to boot). I took care of minor scratches to the metal rods with some rustoleum oiled bronze spray paint. It looks awesome. My issue is the globes. They are narrow and are perfect for the pendant. As I was cleaning them, what I thought was dirt was actually a scratch on the coating on the inside of the glass shade. It is small but I know it is there and it will show when the light is on. Should I spray paint the interior of the shade? If so, what do I need to use and how do I prevent screwing it up. I really do love these fixtures and I want to handle this correctly. Thanks in advance for any help you can offer.

I can't really make out how the globes attach to the fixture from the pictures. Normally I would think a washer inside the globe would work, but that doesn't look possible with the new globe. But, I think that you could attach a washer, if you can find one that is large enough yet has the opening size that you need, to the top of the globe. Maybe something brass so it looks like it should be there. You would need a very strong, permanent adhesive, something like JB Weld.

Remove one glass shade and take it into a local store that carries glass shades to compare the diameter. That should tell you if it's an unusual size or not.

Thanks everyone. From a bit of digging I think I’ve found the type of product that I need: https://www.grandbrass.com/category/holders-neckless_ball_shade_holders-inserts/holders-neckless_ball_shade_holders/
