Need to do some serious scrubbing but have no use for the karate-boosting power that hours of waxing on and off will get you? Lifehacker reader isaacws shows us how he does some serious boat polishing using by hooking up a bathroom brush to power tools.
I came up with this method to polish the top of my boat. I wasn’t sure how to get the oxidation out of the textured surface, so I came up with this method using a bathroom brush and a saw.
All I did was use a metal blade on the saw to cut a groove into the handle of the brush.
I then used some hose clamps to hold the brush to the metal saw blade:
…and wrapped them with electrical tape to protect anything the clamps might hit and to make it look tidy.
When asked whether the intense scrubbing power of his franken-gadget left his boat paintless, isaacws replied:
I used a buffing compound that wasn’t too coarse and it did a nice job of removing the oxidation. It doesn’t scrub enough to get through the gel coat, at least with how I have used it. You would have to scrub a long long time to do that with the compound I used. I suppose a 1000 grit compound could do some major damage.
So there you have it. The desire to avoid a ton of manual labour and little ingenuity win again. It’s like the old saying: Necessity is the mother of awesome power-cleaning tools.
