Greetings everyone , I'm new to the forum. I'm having a hard time with something and I'm finally getting myself on to a home improvement forum. I guess I'll get into my question. I'm refinishing a Sunrad reccessed radiator for a bedroom I am renovating. The other week I applied paint stripper to remove the old paint and then powerwashed the unit with my 3500 psi powerwasher. It cleaned up nice , but when I put the unit in my garage right after power washing the next morning the radiator was of full of surface rust. I'm pretty sure I can power wash the surface rust off but how can I prevent the rust from coming back after the power washing? I can try to dry the water faster.. Is there a solution I can spray such as paint thinner to prevent the rust from returning?
