Painting engine case - to prime or not to prime?

[Oddjob]

Wonder why Honda did that with the front bolts on the KZ engine, by leaving the top of the bolt hole exposed it invites water to enter and rust the screw into the casing, so it either snaps when trying to get it out or rounds off or strips the thread out. I'd fill that up with some grease if I was you, poor design.

I think I used two - it allows for some waste when blowing out the paint with the can upside down - plus some left overs for touching in if needed..
