I scuffed the van floor with sandpaper gave the Protectacote a good stir so the bits were even and applied it after also giving it and good clean and Hoover from sandpapering,gave it a coat one Saturday morning and then another that same evening. It looks just as good as speed liner when it’s done although it’s not as hard wearing you need to touch up well used areas every 12 months or so if you feel it’s needed.
