Why can't you have rusty petrol tank shot or bead blasted ?

Top tip for people wanting a 12V power supply ..... If I remember rightly...the yellow output leads from PC power supplies are 12V. Black is the common ground.

I used one to make a 12V DC supply for a hobby charger power supply. You bundle together the yellow leads together to form a single output. Mine was a 450W supply. At 12v, it will handle 35A draw. It was sitting in the shed gathering dust. Lots of YouTube vids on how to do it.

I've ordered the Sodium Carbonate, I gave my old 4 amp trickle charger to my brother so I will borrow it back from him as I have sold all my old PC's. I will post pics of the froth once I get started! :D

I have used this technique in the past with great success... But watch out, last time I mentioned it on here i had one of the resident “experts” telling me it didn’t work... even though it did 😄

SteveW:
I think the trick is to leave it hours to do its thing, keep water topped up.
Think I put a bit more bicarbonate in half way through as well.

Rob62:
Yep.... i left mine overnight, although i must admit i was a bit nervous of leaving it... The amount of crap and rust that came off was amazing though..
