    Prevent black streaks -- don't clean them. StreakStoppers are the ideal black streak prevention solution for any boat. Designed to mount just under the rub-rail at each deck drainage point, StreakStoppers are virtually invisible once installed.

    Simple and effective

    They are easy to install. They blend in with the boat. Very effective, no more dirty streaks down the hull.


    StreakStoppers do what they are intended to do

    I have been using StreakStoppers for over 10 years. They do exactly what they are intended to do, direct the water stream off the boat so black residue marks do not form.

    Expect to replace them every few years. UV light makes them brittle and hanging fenders will then tend to crank them if you are not careful about fender placement.

    Installation is not difficult once you figure it out, but easiest do do it when the boat is out of the water.

    Great product at good price

    I really like these drip guards. The only thing I wish was better is how long they last. They tend to get brittle and break more frequently than I would expect. Otherwise a great product at a good price that works well.

    Great Streak Preventers!

    • Easy to Install
    • Sturdy
    • Inexpensive
    • Does the Job
    • Non-Yellowing
    • Attractive
    • Gets Brittle Over Time

    This are the best streak preventers I've ever used. Cutting a piece of eisenglass works, but this are stiffer, hold up better, don't yellow, and maintain their shape. They're made out of a translucent 3M product and hold up well for years. I occasionally have to replace one every three or four years because they get a little brittle and break. Easy to install under the trim on your rubrail and have had absolutely no streaks on the hull since I started using them 10 years ago. Great product for the price.
