After molding my own windsheilds recently, I can't think that these
would be a good idea. Acrylic softens at below 300 degrees F and I
think those elements get pretty close to this (locally) I imagine it
could potentially cause localized areas of melt/stress. Of course the
best information would come from buying one and testing it out on some
acrylic to see if it affects it in an undesirable manner.....

Anybody try one of those automotive rear window electric grid element defroster
kits for defrosting a portion of aircraft winshield?
