I’ve got an old, but perfectly functional, Bosch dishwasher (sgv43a03gb, but this is a more general question.)
The top and bottom baskets both have small rusty patches — three or four small (5mm or so) places where the plastic coating has failed and the metal below is visible and rusting.
I’ve tried rust-killer then a couple of coats of Hammerite to fix it, but that only lasted a few months. Before I give it another go (and prepare it properly this time — grind back to bare metal, rust killer), is there anything recommended that’s going to be harder wearing than Hammerite as a top-coat?
TIA!
