It seems hard to get the Traxxas stuff but my LHS carries another brand of 500K.I think its Kosho but I need to look at my bottle.I will get back to you.If you need it call Hobby Hut in Audubon PA or I can pick ya some up and ship it over.The 500K is what I like in the center for sure but for my basher(that I sold) I was going to try the Bad Horsie stuff that I picked up.Its thicker than the 500K.I thought I got an email from buytraxxas.com that the 500K was back in stock.
