please be careful regarding your eyes. High levels of UV and eyes don't mix and could lead to cataracts.
Good counsel! I tend to be a little cavalier about these things, but eyes (or even damage to skin) is nothing to be cavalier about.
I tried something new on Monday; I used some plastic wrap, but instead of covering a "deyellowing chamber" with it, I covered each piece separately. I slathered each piece with the 'cream mix' I'm using, then covered it with plastic wrap just as one might seal up some food for storage. Seemed to work well... the cream didn't dry out (although I opened it up at the half way point and refreshed it) and the UV easily penetrated the plastic wrap.
About the UV; two thoughts:
1) Distance from the UV light is important. For Monday's treatment I had the lamp more like a meter away from the parts. One was just OK, and two of them were much improved, but not satisfactory after six hours exposure. Output diminishes by the square of the distance, afterall. They'll get a second treatment today.
2) UV penetrates amazingly. It takes strong UV blockers to stop skin damage (will even penetrate a cotton T shirt). I'm confident the UV pentrates the opaque cream I'm using and sundry other mixes, unlike visible light.
I'm off to redo some parts today (March 31) and start some other parts. I think I'll do two batches; one with the Sun lamp and one with a black light.
I welcome suggestions on large blocky items (cpu cases and monitors) and I'll report back on my results!
