Works great on rust - but what I found is that hands down, it takes paint off better than any other method I've ever tried. The paint literally sheets off - what ever is left comes off easily with a power washer. With a radiator you will need a bin that covers at least half of it at a time - then flip it to do the other half. (or build a larger tank) I do my tractor hoods and convector covers like this. I've tried grinders, wire wheels & chemicals & have a hefty compressor / blast cabinet combo - but if it fits in the bin - thats where it always goes. Basically fill bin with water, put some washing soda in it, immerse item, connect it up to a battery charger or other power source & walk away.
After its done, you can get a gallon of Phos Etch metal prep from Home Depot & apply with a spray bottle to prevent flash rust form forming.
