Miles' boot floor is welded in and primered. The edges  to
be welded were treated with Hi-Zinc mig paint pre assembly
so hopefully should be rust resistant - more or less galvanised
by the heat of the welding. and I have a big tin of Isopon zinc
paint to go round underneath and give anything thats the least
bit exposed a good coat before spraying on Rustkote and a
layer of Waxoyl . That just leaves the panel gap between
the floor and body which originally was beaded with a mastic
of sorts I am leaning towards a silicon polyurethane sealant
similar to http://tinyurl.com/22wqbu  or
http://tinyurl.com/2y98pq   any other suggestions
that don't involve not sealing so the water can run
out through the gaps?
