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!
Thanks
