Hi all, not directly linked to window cleaning, but however, I do gritting in the winter, I have 25kg bags of salt in the back of my van and a hand spreader. It doesn't matter how careful I am the back of the van gets covered in the corrosive stuff, and within weeks the van can go rusty.
So my question - what would be the best plan to waterproof the back of my van, should I fibreglass it and the protecti - coat paint over that, or is there a better option?
Thanks
