 |

I know that primer(over steel) is designed to provide a base for a top
coat, and (allegedly) you should not leave steel with only a zinc
chromate coating (although I've seen steel fuselages zinc chromated
only and they appear in good condition).
I have read that if you appy a 2-part epoxy primer, you don't need a
top coat. Anyone else read that? - Mike |

If you like the color of the primer then a top coat will only add
extra weight. IMHO

The paint companies around here (PPG, for instance) say that primers
will not protect the steel long-term -- you need to apply a top coat to
seal it.
Check with a good auto/marine paint company -- they have a wealth of
information at their disposal. |
