Hi Richard
Go for the line x . their head office is in barnstable. It really is amazing stuff. I had mine sprayed straight to the floor and about a foot up the sides. I can get in the van and pressure wash it out and it comes up like new everytime.
It also cures in 3 seconds they were in the back of the van spraying it and then walking on it, I think the speedliner takes 3 days.
Cheers Goron
