Found this while searching around, having found more expensive versions dyed hyper-green. promoted on sites selling to the BMW accessories aftermarket. This is much cheaper, if you don't mind waiting for a couple weeks for shipment from Japan. Great on much of the dash and center console: a gel that only an octopus could love, which picks up dust and grit from very hard-to-reach places. I bought two- the second's for the engine compartment, where results have been more mixed. For one thing it can't get really into the high beam covers (odd triangular molded plastic), and you run a substantial risk of losing control of the stuff and having it fall down into the engine compartment somewhere. Use on a cool or slightly warm compartment only.
At any rate: me likey.
