OK, I know there is debate that pine, cedar, and redwood products may be toxic to reptiles and other small animals because of the phenols they contain. I also know it's not a good idea to go spraying industrial chemicals in or around a snake's enclosure because of the risk of toxicity. What I'd like to know, though, is whether there are any lists or guidelines regarding what products are safe for reptiles?

I've seen discussions involving custom enclosures (such as John's recent building adventures), where reference was made to using paints, sealants, and other potentially troublesome products. I've also seen some discussion of making terraforms with foam, spray paint, and sealants.

Have any of you used these types of products for creating enclosures or pieces to go within an enclosure? What steps have you taken to avoid poisoning your animals, if any (airing out >x hours, for example)? Have you had any bad results that could be ascribed to your use of chemicals (stargazing, lethargy, going off feed, etc.) and, if so, what chemicals had you used and how had you used them?

Thanks for any input you can give me.
