I've worked with chrome Monokote quite a bit, and here is another tip I have found very helpful. Never EVER put a heat iron to chrome Monokote without a hotsock, or some kind of soft padding, between the iron and the covering. Most covering irons these days are have some kind of Teflon coating on them, and you can use them on most every other color of Monokote with no problems. But if you do with chrome you will see scratchs in the Monokote. In my eye they stand out like a turd in a punchbowl on chrome. I'm a bit of a perfectionist when it comes to covering, but it just drives me up the wall to see scratchs in chrome Monokote like this.

That's my 2¢ worth
