Spray Painting Radiator

[colin H]

Hello folks

I'm spraying an upright radiator using the Hammerite spray enamel. After a couple of coats it looks ok , but the finish is a little patchy . ie , some shiny areas and some flat areas . I've used a full can so need to order another .
My question is , with it being a couple of days between recoating , will I need to sand it down , or just paint it ? Can't find much info on the can .
Thanks

Any particular reason for using that paint? I just painted them with brushed on, acrylic paint, to freshen them up, and they look fine.
