Re: [PSUBS-MAILIST] Fogging

    Hey,

    If I'm not mistaken, you can get defogger retrofit
kits at some auto parts stores, and I'm pretty sure
most dealers make them too.  Wouldn't be too bad to
adapt it to a sub rather than a car window, would it?
I know for sure there is a repair kit for automotive
defoggers, where you can apply a conductive liquid
(comes in a little bottle) to a break in the element.

                                     Chris N.
