I'm building some outdoor benches using untreated 2x3s for a local youth sports club. Since they're mainly glued together, I'm concerned about their durability when left outside all year in a four-season environment with little maintenance. I understand they'll eventually deteriorate, but I'd like to prolong their lifespan. I'm considering priming and painting them, plus applying Flex Seal to the bottom six inches of the legs to prevent water damage. However, I'm worried that paint might cause the benches to retain moisture and accelerate rot instead. What do you think is the best approach: paint or stain?

Paint does tend to resist the elements better, especially if you use a glossy finish. However, it requires more effort with additional steps. Plus, painting allows you to use fun team colors! Just keep in mind that some say stains coupled with a good exterior wood sealer can last longer and let the wood breathe, which is great when you can’t do regular maintenance.
I prefer using latex stain! It's straightforward to apply, especially on softwoods, plus it requires very little upkeep. It really enhances the natural look of the wood too.
Both options can work, but I recommend finishing with a heavy coat of polyurethane for added protection against weather wear. It'll give you a solid barrier that holds up well outside.
If you’re not planning on maintaining them regularly, penetrating oils might be the way to go. When paint or other film finishes crack, they can trap water against the wood, making rot worse. Stains usually penetrate better and allow for some breathing, so I’d look into that option.
