I haven't had any issues but I always spray my baits down with corrosion x when done with them. One thing to remember is the extra buoyancy of saltwater. Slow sink rates become super slow so I usually prefer fast, extra fast, or floaters.
The Jr. doesn't have a rattle but has a mild knock from joints clacking. The rat has a rattle and knocks pretty loud.
It's my friends 7 foot piece of floating wood. We have a 10 foot aluminum now as well.
Thanks Mike E!
