I'm making cabinets for the garage and laundry room. I'm not concerned about the particle board since we've had a PB cabinet in the laundry room for 10 years and its still fine.
I already took the rest of the OSB back and replaced it with particle board for the other set of cabinets and the lockers I will be building. 4 coats on the inside and bottoms of the OSB carcasses and they still look crappy. Luckily I'm doing pine face and pine shaker doors that will paint and look nice.
