@Charlest- How are you doing Jeff? I understand exactly what you mean re: the inconsistency in labeling standards for various abrasives, that is exactly why I went looking for this article after puzzling over what I saw in Home Depot today. I know most bowlers may not use the lower grits, but as you know from my earlier thread, I've had to run everything down to 400 grit sandpaper in order to get a reaction on my Tuesday night league. I was standing in Home Depot today and saw only two brands, 3M and Norton. Some of the 3M was marked with P, but not all. None of the Norton was marked, but it really felt to me like it was graded on the FEPA standard. That research, confirmed by the article, was critical in me understanding which sandpaper to pick up this morning. I am amazed at the lack of consistency the manufacturers are putting into their labeling when they freely admit that they either use a mix of standards, and use the European standard without marking it as such. I was as interested to find that the article admitted to that lack of standardization among all the companies as I was to read about the definition of the standards. Glad you enjoyed the article, and thanks again for all your expert help in this area in the past... R)
@Matt - Good to know I am not alone on my thoughts about the inconsistency of Abralon! For a while, I thought I was going crazy, but I am definitely going back to sandpaper for consistency.
