Botton Paint Question

[gcolton]

I just finished cleaning the props, shafts and struts of the summer growth.

The marina that last painted the bottom painted shafts and struts. After cleaning they need painting again.

My question. Is it normal to prime the shafts before applying the paint? Or do most just use the bottom paint straight on the bare metal?

It just seems logical to me that some primer like zinc chromate should be applied first.

Seven months and the zincs are also shot. Must have a marina problem.

When I have a bottom job done, they clean and epoxy primer the shafts, struts and props then but the bottom paint on. Prop paint lasts until ya splash it, but the shafts and struts hold up pretty well with bottom paint.

Now that is interesting. I just looked it up and it is certainly recommended over bare metal. I had never heard of expoxy primer. I will see what our local stores carry.
