RE: Goldberg Extra 300
Ultracoat (oracover) has an adhesive that activates at a much lower temp than Monokote. It is easier and more consistant to work with than Monkote. The film stretches at a lower temp. All around it is easier to work with.
But.....
If you use lighter colors, Ultracoat has a transluscent quality about it. You can see the wood grain through the color pigment.
I also think (This is only my OPINION) that the colors just aren't as full as Monokote.
There have been some changes our EPA has enforced to the adhesives on Monokote that have caused a little consternation. The quality of the product has been inconsistant. It is frustrating, but I have maintained the patients because I like the full color and brightness better than Ultracoat.
