I want to re-paint my radiators with eggshell. They are currently painted with gloss (probably hundreds of layers). What is the best way to prep the radiators?? Do I need to remove the old paint altogether and is there any recommended products or will it be ok if I just sand them down to smooth the surface? I plan to replace them at some point so dont want to do the job at too much expense, but not afraid of hard work.
Any advise would be greatly appreciated!
