Also check the metal gearbox oil pipes which run into the rad - mine were very rusty and wouldn't have lasted much longer. Huge bill potential if they rot through!!
Thanks. Proper paint, it's satin 'Ebony Black' sold by COO-VAR and is oil based. Marketed as a restoration product to get round the Greenies hatred of anything with high VOC content I use it for the suspension on the 107 and is really hard-wearing.
