I have and use all three Opt products: OOC, OID and ONR at QD dilution. OID leaves a slicker finish, but I'll only use it for the light dust that accumulates on a indoor parked vehicle. Anything more gets OOC as I feel there's a larger tolerance for dirt. I use ONR at QD dilution if I need to remove any dust between polishing or waxing steps as well as for glass. BTW, OOC is also very competent on all surfaces as an interior QD.
