FAQ
Q: Will it wash off in the rain or at the beach?
A: Nope. Captain’s Seal is water-resistant and built to stay put, even in wet, salty, or humid environments. That slightly tacky finish helps it stick to surfaces and keep moisture out.
Q: Is it safe to use on paint, rubber, or plastic?
A: Yes! It’s non-toxic and safe on all common surfaces—painted areas, plastic trims, rubber seals, wiring, and more.
Q: Does it stop rust that’s already started?
A: It won’t reverse rust, but it will slow it down and help prevent it from getting worse. For best results, remove any loose rust or corrosion before applying.
Q: How often should I use it?
A: Depends on how exposed your gear is. For boats, trailers, and 4WD underbodies, we recommend spraying every 3–4 weeks or after heavy use. For tools or fishing gear, every couple of months is usually fine.
Q: Can I use it on electrical connections or battery terminals?
A: Absolutely. It’s a great way to protect terminals from corrosion. Just use a light spray—don’t flood it—and make sure the area is dry first.
Q: Does it leave a greasy mess?
A: It leaves a light, tacky film, not a thick greasy layer. That’s how it blocks water and salt. If you over-apply, just wipe off the excess with a cloth.
Q: Can I use it indoors, like in a garage or shed?
A: 100%. It’s great for protecting tools, machinery, hinges, and anything metal that sits unused for long periods.
Q: Does it smell?
A: It has a mild lanolin scent—nothing overpowering. No harsh chemical fumes like some industrial sprays.
