So... not so quick an answer to a not so simple question! But it is a great topic , thanks for asking it!
My Molybdenum DiSulfide arrived yesterday and I had a chance to play with it... and yeah it is awesome stuff... far superior to graphite alone. Instead of 6-7 second wheel spins it is upwards of 10 with just that addition. So graphite Moly blends will be far superior to graphite alone. And as Dr. mentioned, his moly alone may or may not be best, but you should check it out as it is an improvement. My first ever car entry recently was .1 second off first place... and there were a host of cars between first and last... maybe this stuff will get me in range? I can definitly see and feel the difference.
Has anyone tried teflon powder? I'm considering getting some and seeing how it compares
I tried the ptfe powder as well... I had a hard time getting it to flow into the wheel hole.. it says it is ultra fine...
Did not seem to yield any improvement for me, but supposedly it is more slippery than either graphite or moly... IDK, I keep going back to silicone spray as maybe the best?
Teflon powder any good?
Here is a good link to a PWD discussion on teflon powder if interested
I use the pinewood derby graphite from Hobby Lobby. It sits loose in a ziploc bag while wheels are in there so the axles get coated from head to toe. Makes finding a matching pair pretty messy but they spin for a loooooong time.
