Found 13th Feb 2017
I bought this Johnstons Smooth Metal Silver paint from the Newton Abbot branch at the weekend for £2 for a 750ml tin, they had it in a smaller 250ml for £1. They also had white radiator enamel paint for £1 a tin 250ml, plenty of stock to clear out. Its water based too I believe so easy clean up. Not available at Trago online.
