Now I slap on a dab of clear nail polish over the heads—my wife thinks I’m nuts, but it actually slows the rust down.
Honestly, I get the logic—anything to keep that salt air from eating away at metal. But even “marine” hardware isn’t always up to the task. I’ve had better luck with stainless fasteners, but even those eventually show some staining. If you ever redo the deck, powder-coated or composite railings might save you a lot of grief... though they’re not cheap. Maintenance near the ocean is just a different beast.
I’ve seen folks try everything from nail polish to duct tape to keep rust at bay—sometimes it works, sometimes it just buys you a little time. Had a client swear by Vaseline on screw heads, but that just turned into a sticky mess after a few months. Even stainless isn’t immune out here; I’ve seen “marine grade” stuff pit and stain faster than you’d think. Honestly, composite railings are pricey, but I’ve yet to see one rust. It’s just a trade-off between upfront cost and ongoing headaches...

Ain’t that the truth. I’ve swapped out “marine grade” fasteners on roofs more times than I care to count—salt air just eats ‘em alive, no matter what the box promises. Tried that Vaseline trick once too, but it just collected grit and made a mess. Composite’s expensive up front, but at least you’re not chasing rust stains every season. Sometimes it feels like you’re just picking which headache you want...

Funny thing, I actually went the composite route on my deck railings—looked great for a while, but after a couple years the sun faded ‘em and they started to warp a bit. Not as maintenance-free as I hoped, honestly. I ended up sticking with galvanized for some stuff, just swapping it out every few years. It’s a pain, but at least it doesn’t cost an arm and a leg all at once. Sometimes the old-school fixes aren’t the worst option...
- Composite’s definitely not a magic bullet, especially near salt air. UV and heat can do a number on it—seen plenty of warped or faded rails in my inspections, even on newer builds.
- Galvanized is decent, but that coating wears down faster than folks expect when you’re close to the ocean. Once it’s compromised, rust creeps in quick.
- Stainless steel hardware holds up better, but it’s pricey. If you’re swapping out galvanized every few years, might be worth doing the math on stainless for high-exposure spots.
- For wood, regular sealing helps, but nothing’s truly “set and forget” out here.
- I’ve seen some folks try powder-coated aluminum for railings—less rust, but the coating can chip if you’re not careful moving furniture or grills around.
- Honestly, no perfect answer. Everything’s a trade-off: pay more up front for less hassle later, or budget for regular replacements. Just depends what bugs you more—maintenance or big bills.
- If you do stick with galvanized, hose things down every so often to get rid of salt buildup. It won’t stop rust forever, but it’ll slow it down a bit.
