Ok, so after having no luck with the B&Q stuff i went and bought some Nitromorse and painted it all over the cover
Left it for a bit and gave it a 2nd coat, left it for 40ish mins then attacked it with a wire brush
It didnt work to well so i gave it another two coats and wire brushed it again
A little disapointed i took it to work and spent 3hours with emery cloth to get this
Going for paint tomorrow
