I have also recently discovered mosaic's and was'nt sure if I should trust them, but with a good epoxy and proper prep your handle scales will be well secured with the combination and mosaic's are an attractive handle accent! I peened my handle scales for awhile but have come to the conclusion (with only short term results to draw from, and advice from several others here) that peening is a bad idea. There are alternatives that allow you to have a mechanical connection, I want to call them "Loveless bolts" but not sure if that is correct. Basically it is a bolt in the form of a pin and after it is installed you remove the screwdriver slot to leave what looks like a plain pin! I believe mid - west carries them! Hope this helps!
