All protectors need to be applied to new or freshly cleaned with no detergent residue.Surely if the seating was new then theres no problem with the 'green' one.The only problem I could see was if the green one was water based and the fabric was water sensitive.Mike
It depends on the flock, if it is quite heavy/dense then its worth misting first with water or else when you spray the protctor on it will absorb and penetrate very quick and you will go through loads of protector, which isnt a prob, but just costs you twice as much.
