I’m not so sure Future Armour has SiO2 in it. I believe it is a traditional polymer spray sealant, but I could be proven wrong.
If I’m right it would explain why it does not have as good self cleaning as Wet Coat, which I would guess HCW would be similar to, given they are both SiO2 infused products which typically have good self cleaning ability.
Future Armor should be also a SiO2 Product. So are there any experiences with HCW and self cleaning?
