You're right, I think you do get what I mean. Man-made could probably have been the exact term that I should have used. Shrink, expand, reacted to, sanded easier than adjacent material or what ever reason. You learn of it when you actually use it.cutter said:Sorry Bandido, that stuff is thermoplastic and not phenolic. So scrap that theory that it proves phenolics swell. Probably either reacted to solvents in the finish or was sanded or polished to hard and got hot. Thermoplastics especially polyester based stuff will act strangely with solvents and heat.
