Is Castrol Chain Wax really wax? When I took my bike to the shop to get some work done, I had a new sprocket and chain put on. The chain looked as though it had a legit wax on there (white "residue"). Just picked up this Castrol stuff, cleaned and lubed the chain, and at first I thought I didn't put enough on. Didn't see much of anything on the chain. But lightly touching a link revealed that there is indeed something on there.
After less than fifty miles, it looks like some sweet gunk and grit is already building up between links/on the cog...
...so is this stuff any good, or should I switch to another brand? It's gritty and sandy out here. No rain or wet to speak of.
