When cruising or taking your family for a boat ride, you don't want it to look like it has been in store for ages and you've never brushed its surface. Oxidation will change the color, look, and texture.

It is important to wet sand your boat to achieve a smooth and polished appearance that looks beautiful on the water.

What You Require

How to wet sand a boat can call for different tasks and processes. Doing it yourself is often better than taking the job to a polisher, who will likely charge a lot of money.

To minimize the high costs, all you need is:

  • grit - either 1000, 500 or 200.
  • soap for the sandpaper. The soap helps to improved traction; this is like reducing the friction between the boat surface and sandpaper material.
  • a bucket of water.

It is helpful to try these processes at home. This way, you can learn how to select the best process for wet sanding and learn which tools can accomplish it effectively.

The Process

The process of wet sanding will differ based on the surface and degree of oxidation.

Determine what grit will remove the rust. Take a small surface and start from this spot. Notice the changes when using the 200 grit, 500 or 1000. Start with the one which will remove the
oxidation. Then continue with the 500 and 1000. Remember to wet both the surface and the sandpaper with soap and water.

This will be followed by adding a compound for polishing. A polisher compound such as Collinite Auto may help for waxing and sealing.

If done correctly, the outcome is a new shiny boat that is smooth as glass, attractive and sleek. I'm not a fan of boat collections (I would only own a couple of boats max at one time), but following this process can make your boats look like gold.

Now you're ready to take your family out for a ride on the water. Enjoy!
