I have a couple of thoughts around this Manish:
The cyclicality of the abrasives industry is smoothened out to a large extent by the fact that the cater to a whole host of industries across the economy. GN does not have an exposure greater than 15% to any one industry. CUMI and GN both manufacture silicon carbide which is the RM for abrasives.
Another point is that the quality of manufactured products in India is improving in terms of functionality and aesthetics. The grinding and abrasion processes contribute to this.
Yes I do agree with you that if the economy tanks then abrasives will hurt, but then again if the economy tanks everyone will hurt
