Sim Jim put me on to this stuff to prep my plastic stock for him to copy in a laminate blank, Now that I have done it it is actually a good practical solution for someone who wants a comb raiser on a plastic stocked rifle, I didn't spend too much time over the final finish as I plan on modifying the looks a little prior to it being copied. In terms of fit however it is first class, I have now sent the action to Andy to fit the new barrel but with the action in and a 50mm OL scope mounted in low optilocks it is perfect.
If you want a better cheek weld due to using a big OL scope its worth a try. Its sets nice and hard and yet is removable apparently. Great stuff!
