I've used it and don't like it any better than any other iron-on film. I used it on My Stik 30 and the black bubbles horribly in the Florida sun.
A lot of people will tell you that UltraCote (same as Oracover so I've heard) is better than Monokote. I haven't had any better or worse results with any particular brand. They're all sub-standard finishes as far as I'm concerned.
Aren't you glad you asked.
