Since most people can't tell if it's there or not (as evidenced by the threads asking about wiping it off, how long it lasts, etc...), I think I'm going to start selling "oleophobic coating in a jar".
"For the low low price of $39.99 ($5.00 discount for MR users!) you too can re-apply the coating you can't even tell you have!"
Send me orders.
*Product may or may not work, and may look suspiciously like a jar of air.
