Not arguing with you, and I understand your concery. Every cast I've done was sticky on the surface that touched the air but were always cured hard all the way through. I have had some that never cured but I think I altered the chemistry by adding the wrong kind of colorant or too much of it. Most of what I cast are snake skins and they always cure rock hard. I have 4 or five colored casting and the pens are as hard today as they were 18 months ago when I cast them. I have my system and it is working for me. I think once the resin cures, there is no uncuring. Not trying to convert anyone, just relaying what I discover so we can all have fun casting and I know that is what you are doing also. And you gave some really good information. Happy casting.

I don't ever want to have a PR blank come back because it got mushy from skin oils or something normally harmless... The first couple i did, never hardened up fully (there's still a mushy blank in my box) and the pen was a little soft after i turned it.. The ones i put on my aqarium light (it's a bit warm up there) to cure are rock solid, and have stayed that way except when i hit them with DNA..
