FWIW - the bottle of "Bondene", which is totally useless for ABS (this kit's wrap anyway), lists "Dichloromethane" as the only named chemical on the label.

Methylene chloride, also called dichloromethane, is a volatile, colorless liquid with a chloroform-like odor.

So I would not dare to trust Tenax without doing a test like I mentioned, on the underside of the kit's ABS wrap to see if it feels "sticky" from melting.... or not sticky (worthless/dangerous).

Actually,l are you sure Tenax 7r is methylene chloride? I can't find a definitive "official" source for what its main ingredient is. A person says MEK, but that's not official. If you do have a bottle, please read what the label say it uses.

Plastic Weld labels says it uses MEK, and bondene uses Dichloromethane.

OK, I later found other sources saying that Teanx IS made of methylene chloride / dichloromethane.

A commenter on a model train forum said "My experience with Tenax has been best summed up with "Spit and water holds together better than that"."
