"I used the airtight and epoxy and, as we speak, my bobblehead statue of Caesar (from Caesars Indiana) is standing on the chip, securing it on the painting."

Here is how I do it. I use clear 5 min. epoxy. I hold it to the frame with a spring clamp. I don't or wouldn't put any weight on the chip. When it dries I place the chip in with the other half of the airtite. Barry
