Question is the title of the thread. I’m doing to 4 hole injector swap and would like to paint my rusty rail. It looks like it originally had black paint on it. I have a can of engine enamel with ceramic paint (high temp).

 

Yeah, it's just fine. Don't get the paint in the cups where the injectors go.

 

Thanks! I like how it turned out. New 4 port K suspension injectors are doing great so far. Had 2 rough starts and then it evened out great.

 

 

That looks good.

 

Nice!
