The thing on your warranty with Ethylene Glycol has caused people to start citing your website as a source as to "the fact" that EG shouldn't be used with ANY acrylic products.
Could you please either revise your warranty to no longer say this or explain why your acrylic is different than other acrylic and therefore is for some reason not compatible with ethylene glycol.
Alcohol is a no brainer yeh duh it isn't compatible but they are not similar as some people believe.
This is (3) places that claim EG is compatible while showing alcohol as not being compatible.
If you could just simply explain the difference in your warranty that would be great... otherwise it just sounds like you are playing an uninformed game of CYA!
