Which primer is best to use when priming gutters and shutters outside, a water base or oil base?
Howdy i prefer oil base for its adhesive and long life. I pick the paints that allow a oil base primer with a latex top coat. I use semigloss top coat as it wears better over time
Really depends on what the shutters are made of...
If they're a plastic, definately use a top-notch LATEX primer. Plasic expands/contracts more than wood typically, therefore Latex is called for.
If they're wood, use either primer. Just make sure the surface is clean, and IDEALLY...lighly sanded.
Gutters...if metal...lightly sand & de-dust. Zinsser 123 or C2-One are great Latex primers on metal.
I would concurr with Faron on both accounts.
Definitely use latex/acrylic primers on plastic shutters.
I too prefer latex primers on metal gutters. Many years ago when galvanized gutters were very popular, I stripped many gutters down to bare metal and then primed them with latex based primer and top coat. I NEVER had a call back!
Actually, If you are painting over existing seamless aluminum gutters, a primer is not absolutely neccessary. After a good cleaning to remove dirt and oxidation, simply paint them with a quality 100% acrylic house paint. Over the years, I have painted over much degraded aluminum siding and gutters with quality acrylic housepaint and never had a problem.

Ordjen points to a great website!
That place is a "Bible" of paint info./techniques.
Highly recommended for "paint-geeks"!
A couple hours of study there, and you'll know more than many painters out there!
