I'm fine with the factory rockers, but the ceramic coated shocked me. Now this may be common practice, without issues, and I just never heard of it.
I do have industrial experience with coatings. One thing for certain is that coatings can come off. Ceramic tends to hold up well if the base metal that it is on does not flex too much. And too much is not very much. Ceramic is strong, extremely hard, and brittle compared to steel.
Why bother to add ceramic to a rocker that lasted 50 years, without it, given that if the ceramic comes off it will be bad? I could be totally wrong here and may get educated by the answer.
