Hi Eddie, If I knew how to, I would put a paper I collated about this subject on the forum. Call me a luddite. However, if anyone cares to send me an e-mail, I will forward this document. Restom is the one I used, available from JP Classics in Southampton, SO4 2GP. I have heard good things of Slosh from Draganfly Motorcycles, Tapox from Caswelleurope and Tank Cure from LB Restoration Services. Cheers, ET43
