Besides all the usual wood, plastic, granite, and cermark stuff I've always done, I narrowed it down to 2 new items.
I etched some dichroic glass. Small designs that were put into a kiln. Looked great when all done.
I've also been cutting an iron-on heat shrink film product for model airplane use called Monocote. I assumed it is polyester- can't find an MSDS sheet for it.
My lens has a film coating I can't clean off with regular lens cleaner. It's blotchy and I'm afraid to wipe it any harder. It almost lookes etched on. I'm thinking of soaking in acetone or vinagar for a while. My aircone was also coated with pure white ash, which washed off easily. That really puzzled me. Has anyone lasered any of these two items before?
Thanks,
Tom
