Absolutely.

Great, glad we agree.

I wouldn't try to talk someone out of a product that I haven't used.

I'm interesting in hearing about your experience with the GE Silicone Glazing. Please share your experience.

water based products are far safer than solvent based.

The primary benefit of water-based products is easier cleanup, but the down-side is often harsher chemicals need to be added to get the components of the product to blend. Think about oil and water - they don't mix, and even if emulsified will separate, so a chemical emulsifier is required.

That may be why the water-based Polyseamseal is more toxic than silicone - it's the chemicals they have to add to make the water-base blend.

That is a common misunderstanding.

I understand your misunderstanding. Most water based products don't contain oil. As for Polyseamseal being more toxic than silicone, the major ingredient which is listed as toxic is n butyl acetate.
From Wiki: n-Butyl acetate, also known as butyl ethanoate, is an organic compound commonly used as a solvent in the production of lacquers and other products. It is also used as a synthetic fruit flavoring in foods such as candy, ice cream, cheeses, and baked goods. Butyl acetate is found in many types of fruit, where along with other chemicals it imparts characteristic flavors. It is a colourless flammable liquid with a sweet smell of banana.

I doubt there is anything in silicone that would be edible.

So, my suggestion for you is to use what you please.

IMost water based products don't contain oil.

I agree that common sense would seem to suggest that water-based products wouldn't contain "oil", yet virtually all water-based products do contain organic oils such as the n-Butyl acetate you mentioned.

Silicone is used for medical products and in many food products, including some candies. As the health rating on the MSDS shows, it may be safer to ingest silicone than drink alcohol.

As I have noted previously, though, my Ph.D is in electrical engineering, not chemistry, so I'm going to defer to the chemists on this forum for a more thorough explanation.

I don't see value in debating it further. We have shared our information and it's up to the OP to make his own choice.

I don't know about that. I've seen a couple things that had silicone in them and they looked very edible to me.

Food value might be low with them, but I agree totally!
