Eric, you're singing my tune ! I've used that stuff for many years now and it is really great.
It was developed here in Richmond Hill, Ontario, Canada by DW Electrochemicals. As you know only a very small amount is needed on the surface to be effective. The last bottle that I purchased here in Waterloo cost around $35.00. I'd bet that Electro-Sonic would carry it and they are now in the Buffalo area....might be quite a bit cheaper than the Motorola price...
