Methanol, Ketones, and Ethanol.
This stuff work out stev?

Yikes! Forget using the stuff if it has methanol. Methanol is a nasty substance to a cooling loop and your health too! Just return it for a refund.
It may be denatured, but it has additives. Therefore it's not absolute ethyl alcohol.
Does your local town liquior store sell collector sample bottles of 200% proof vodka? It would be the size of about two shot glasses. Usually that sells for under $5.
As for water and alcohol, yes they have similar effects. It's just that water has the best pH.
Alcohol and ammonia can have similar affects to acrylics. Usually the acrylic surfaces becomes crazed as in the crazing effect. This can happen readily or over night. A good example of this is old plastic car headlamp covers that were once clear. Windex (ammonia) or any other alcohol will do hydroscopic damage. Once the air hits the plastic and the plastic dries out, crazing or cracks will form.
