Looks great! I just love how electrolysis works on rust. Kind of like magic IMO.
I have found that Painters Touch “2X Ultra Cover” works the best for Japanning. I have used other products, including other Rustoleum paints, but this seems to cover the best, and it does not seems to chip as readily as others. Picked it up at the local HD Tractor Supply, but I am sure you will find it where ever Rustoleum products are sold.
