    You need a metal primer, an undercoat and a gloss.

    Alternatively, use Hammerite Smooth, which effectively does the samethng.

    I like the thanks button, but ,please, an I agree button.

    Will the grammar and spelling police respect I do make grammatical errors, and have carp spelling, no need to remind me.;)

    Always expect the unexpected:eek:and then you won't be dissapointed
