I saw durability of 2 months parked outside in fairly harsh conditions, not excellent but not bad either. It does contain kaolin clay which is supposedly a filler.Does anyone have an estimated durability of M21? I just put some on my wifes car on one side and some Poorbooys EXP on the other to compare durability. It went on super smoothly and was very easy to take off. It also states in the description on AG's store that it has fillers and will help remove swirl marks. It only states it in the larger size bottle and not the 16 oz. bottle. Is there any truth to this? Might be a good alternative sealer on production details to help hide some of the deeper RIDS and swirls that a one step can't remove...
