I just de-restricted my estoril pipe and now there is a very nice clean weld around the chamber. Obviously the weld and surrounding areas are now bare metal and will promptly rust if left like this.
So what is the best way to remove the clear coat? I assume the paint would start to flake if I painted over the clear coat. Is there a chemical or something? Or is it something best to do with sandpaper and some elbow grease?
