I like Mod Poge adhesive for adhering tissue, film, carbon veil, etc. It is kind of thick. I thought I'd try an experiment to thin it without adding more water and maybe making drying quicker.
So I mixed up some Mod Poge with denatured alcohol. Not a good plan. It actually ended up a thick gel. I tried doing a test sample covering, and it did work, but it was worse for brushing than the original glue.
Plus, the brush was a b%$^h to clean.
I guess water is still the thinning liquid to use.
