Hi,Can anybody tell which paint I should use on bare steel, i have only ever used two pack primer before but have heard a lot about epoxy primers (DP90?). Should i use etching primer then primer surfacer or epoxy then primer surfacer?. And anyone know where i can get it from as my local paint supply guy has never heard of it. I Normally paint all my cars and have never had any problems just wondered if its better for longevity and what benefits it has. Any advice would be appreciated.
