I saw several old posts, but none mentioned which one was better....

The "black" or "blue" can?

 

Im not very familiar with the PJ1, I used to stick with Bel-Ray. I tried the Maxim chain wax and really like the stuff. It doesnt seem to attract as much dirt as the other chain lubes.

 

I use the JP1 (blue can) on all my bikes.
I used to use the belray chain lube but I found it flings off at high speeds and makes a mess of the rear tire the JP1 sticks and willl not fling off.
Its the best Ive found so far

 

I use the blue can on my 2000TBoss. It works out well, I just lube it after every ride/cleanup.

 

Thanks! I purchased the "blue" can. Once you let it set for a few minutes, the chain feels just it did when I brought it home from the dealer.
