Keeping rust at bay when you're near the ocean

Tried those ceramic-coated screws once on my deck rail—figured I’d save a little cash. Two summers later, half of them looked like they’d been dipped in orange paint. Ended up swapping ‘em for 316 anyway. Lesson learned, I guess...

- Seen the same thing with ceramic-coated fasteners on fascia boards—looked fine at first, then rust bled through after a couple seasons.

“half of them looked like they’d been dipped in orange paint”

—yeah, that’s classic around salt air.
- 316 is pricey but honestly, it’s the only thing I trust near the coast.
- Curious if you tried any sealants or just swapped the screws? I’ve had mixed luck with caulks and tapes for extra protection, but nothing’s foolproof.
- Anyone ever use hot-dip galvanized for rails or is it just not worth it with ocean spray?

“half of them looked like they’d been dipped in orange paint”

That’s a familiar sight anywhere near salt air—doesn’t matter what the coating says on the box. I’ve seen hot-dip galvanized hold up okay for interior framing, but for rails and exposed spots, it just doesn’t last. 316 stainless is expensive, but I agree, it’s usually worth the upfront cost. I’ve also tried various sealants and tapes over fasteners—sometimes helps for a season or two, but nothing really keeps the rust at bay long term if you’re right on the coast. Frustrating, but you’re not alone.

I hear you on the sealants and tapes—tried that route myself, and it always felt like just delaying the inevitable. I finally bit the bullet and switched to 316 stainless for anything that’s going to see salt spray, especially deck screws and railing bolts. Pricey, but I haven’t had to replace a single one in five years now. The only other thing that sorta helped was rinsing things down with fresh water after storms, but let’s be honest, who remembers to do that every time?

316 stainless is definitely the way to go near saltwater—learned that the hard way after replacing corroded fasteners every other year. I’ve also had some luck with hot-dip galvanized hardware for less critical spots, but it’s hit or miss. Rinsing helps, but yeah, it’s tough to keep up with. Sometimes I’ll just hose things down when I’m already out there doing yard work, but it’s not a perfect system.
