Coated vs Uncoated Sodium Percarbonate?

[Pat Norman]

I was talking with my chemical supplier Univar about buying a bag of sodium percarbonate for various cleaning uses mainly light deck washing and they asked did I want coated or un-coated. Anyone know whats the purpose of the coated? Do I want coated or not?

Well after a little googling I found that the coated is more stable for storage without clumping.
