The galv trailer has rust on the floor, due to me leaving damp compost on it for too long
Ive googled Rust kill and see most at Bunnings/M10 are more of a rust protection than killing although there are some rust converters
Any recommendations? In most places its 100% surface rust covered, do I need to sand it? If so I guess I can get an attachment for the cordless drill?
End of the day do the so called rust killers actually convert rust to a neutral ferrous solution as claimed?
