Have you (or anyone else for that matter) tried teflon spray? Not sure why I didn't, but I keep a spray around the house for the odd job. The thought came to me when I found recently two types of spray in the shop, a dry and a non-descript (same company, similar cans). Couldn't find any info of the difference. Made by CRC if it means anything.

I'll try next time I open a mini chassis, but if anyone has experience with it already, here's your chance to save us some experimenting.

I found this spray (non descript type) very useful in lubricating plastics (hinges, sliders, etc).

PS. What about the Spice gear diff? Anyone tried that?
