Cavey, as much as the film looks good, be aware it is ultra thin at 2mils, and will show the wood grain easily, no matter how much you sand it..
You need to go thicker (.5-1mm) to hide the grain.
I only say this because we suffered the same thing on a work project, until we used .5mm film which hides the graining effect, although the final product eneded up going with acrylic mirror anyway..
The $15 rolls are on ebay, i just bought some 3-4 months ago, and very similar pricing at local suppliers in vic anyway.
food for thought.
