[neil still building it]

hi andy
i'd agree its not too serious really can you get a finger nail to feel it? or is it just a mark ,either way the correct term is 'burnish' ie polish it out using something very blunt ie piece of rod layed flat etc
even if it is a little deeper there's gonna be loads of oil down there,
so alittle seepage isn't going to hurt in the 'grand scheme of things'
