My 16-year old Iswara is turning rusty. I am seeking this product, 'Kurust', that I've used before and found very effective at treating rust. However, my quest for the product this time has turned nowhere so far, not even from the very outlet I used to get it from. I wonder if anyone can advise where I should look locally (within the Klang Valley, that is). Would be very grateful for some meaningful suggestions. Many thanks.
