Best material to coat playground slide?
So I don't know how it is where you all live, but in my city, ALL playgrounds are closed pretty much indefinitely. And I've got a 3-year-old and a 4.5-year-old ready to tear our house down around us. So I need to build us a playground.
Unfortunately, a lot of other people seem to have had the same idea, which means that the only slides I can find online are either poorly-reviewed or REALLY expensive. So I'm asking: If you had to build a slide in your backyard, what material would you choose for the slickest, fastest, most durable sliding experience?
-Some kind of laminate or melamine.
-A thick layer of tabletop epoxy polished up real good.
-literally just cutting a bunch of PVC pipes in half and laying them down next to each other.
Thoughts? Bonus points if water can be run over it without damaging it.
