This is absolutely correct. Years ago, I worked for a shop in Sacramento that was a dealer for single and multi-engine Cessna's. One of the little touches that we did to all of our planes was to install a chrome spinner. On most planes we really had no issues, but there were some planes that we had real problems with. There was a common link to those problems....They all had high horsepower 4 cyl Lycomings! O(IO)-360's of 180-200 hp. We were continually finding cracked spinners and even had a few separate in flight!
It was many years ago, but I do not remember any problems with the smaller Lycomings or the 6 cyl Continentals.
Once we finally stopped with the chroming, we had no more problems. I made a few extra dollars by polishing new spinners, and as long as the renters and mechanics kept their greasy hands off the spinners, they stayed nice and shiny for quite sometime.
After you get it polished to your satisfaction, I recommend a heavy application of a good wax to keep fingerprints and bugs at bay. I do not know what processes some people, but it seems that they just can't keep from putting their greasy fingers on a fine looking spinner!
