It HAS to be tartan........
Yup defiantly tartan!! Pop down to your local motor factors and ask them for a tin of it, oh and ask them if they've got any "long weights", whilst you're there, they always come in handy!!
....and as it's going to take time and effort, grab a tin of "elbow grease" while you're at it
...and you might as well get some "dehydrated water" for topping up the coolant :)
