Coating part with glass piece

[johnny933]

I want to coat an alum. clutch cover off an atv. Here's the problem. Theres a small glass eye that I cant figure out how to get out. will it break during heating? Have any of you guys done this with the glass view finder for the oil not removed?
Thanks for any help.

I have done a few with them. I usually remove them because they are held in with a seal that may melt during the curing process.

Guess i'll try to get it out one more time. Hopefully i'll have some luck.
