I would paint the floor.
I'm not sure about the stainless thresh, the pictures on the YRM site are too shiny to see what's what. I think I'll email them when I get around to putting it on.
Got the thresh on, took a while to work out though.
I may paint the floor with stonechip, you reckon I need to etch primer it first?
Also got the door on with my nicely painted hinges. Anyone want to give me tips on how to line the door up? it drops too much away from the hinge.
