It can be expensive to repair holes in your aluminum boat hull if you have it professionally done by a welding technician, but it does not have to be especially if you do the repair yourself. By using a metal patch made from very cheaply obtained materials and a little bit of cold welding compound, the hole can be repaired. Then you can quickly be back to using your boat for fishing, water skiing or just enjoying boating on the water.
Here’s what you need to complete the project: a 12 ounce soda can, a pair of metal snips, some cold welding compound, a 2-by-4 wood block 6 inches long, a hammer, some sandpaper, a sanding block, and enamel spray paint that matches the boat’s hull color.
The first step is to cut the top and bottom off of the soda can using the metal snips.
Then as step two cut down one side of the soda can using the metal snips. Then use the 6 inch 2-by-4 block to make the soda can lay flat turning it into a flat piece of aluminum metal. This will be the patch to go over the hole in the boat.
Your third step is to cut any jagged pieces sticking into or out of the hole in the boat off using the metal snips. Then use the hammer and wood block to beat smooth the area as much as possible.
For step four, lay the flat aluminum soda can patch over the hole from the inside of the boat. Then attach the flat aluminum soda can patch by placing cold welding compound over the edges of it to hold it to the aluminum hull of the boat. Wait for about 2 hours for the cold welding compound to fully set before proceeding.
Your last step is to sand smooth the area where the patch was put into place. Use the sandpaper and sanding block to do this. Then paint with spray paint the area where the patch was installed.
