You need a helper with al foil on the end of a stick to hold it up blocking the light, while you look for the leek. This sounds weird.
I'll look for it, as I'm at my wit's end here and about to re-paint the exterior.
It seems no matter what paint I use, or how much, it doesn't diminsh the light bleed. It is almost as if the portion of the backside I am painting doesn't correlate with where the bleed is, but it should though. I am wondering if the styrene of the dish over-extends the acrylic more than I remember.
Look at these photos. I'm thinking the darker grey is OUTside the acrylic, and inaccessible from the inside.
