What Gauge Sheet Metal For Rust Repair: Personal Opinion
The gauge of the metal refers to its thickness, and selecting the right gauge can have a huge impact on the strength and durability of the repair, as well as its appearance.
There are different gauges available, each with its own pros and cons. Some gauges are thicker, making them more durable and suitable for areas of the vehicle that will see more wear and tear. Other gauges are thinner and better for areas that are less visible. It all depends on your individual needs and the specific repair you’re making.
In my opinion, a great option for rust repair is 20 gauge sheet metal. It’s not too thick, so it’s easy to work with, but it’s still strong enough to provide a solid repair. This gauge is also versatile, so it can be used in a variety of different situations. Another option to consider is 22 gauge sheet metal. This gauge is a bit thinner than 20 gauge, but it still provides good strength and durability.
Overall, choosing the right gauge sheet metal for rust repair is all about finding the right balance between strength, durability, and appearance. With a little bit of research and consideration, you’ll be able to find the perfect gauge for your specific needs. And trust me, making the right choice will make all the difference in the end result of your repair.

Step-by-Step Instruction On What Gauge Sheet Metal For Rust Repair
- Determine the size of the repair area: Measure the length, width, and depth of the area that needs to be repaired, including any curves or contours.
- Determine the thickness of the existing sheet metal: Use a sheet metal gauge tool to measure the thickness of the existing sheet metal around the repair area.
- Choose the appropriate gauge of sheet metal: For rust repairs, it’s best to use sheet metal that is the same thickness as the existing sheet metal. If the existing sheet metal is too thin, the repair may not be strong enough. If it’s too thick, it may be difficult to bend and shape to fit the contours of the repair area.
- Cut the sheet metal to size: Use a metal cutting saw to cut the sheet metal to the appropriate size for the repair area. Be sure to leave a little extra sheet metal around the edges to allow for adjustments and trimming.
- Bend the sheet metal to fit the contours: Use a metal bending tool to bend the sheet metal to fit the curves and contours of the repair area. Make any necessary adjustments to the shape of the sheet metal until it fits perfectly.
- Create any necessary holes: Use a metal hole punch to create holes for screws or rivets as needed.
- Attach the sheet metal to the vehicle: Depending on the type of rust repair being performed, attach the sheet metal using rivets, spot welds, or welding. Make sure to follow all safety precautions, including wearing protective gear such as safety glasses and gloves.
- Check for proper fit and finish: Once the sheet metal is attached, check for proper fit and make any necessary adjustments. Trim any excess sheet metal and smooth any rough edges.
- Paint the repair area: Finally, paint the repair area to match the surrounding body of the vehicle.
Note: The specific steps and equipment needed will depend on the type and size of the rust repair being performed. This guide is meant to serve as a general outline and may not include every step required for every repair. It is always recommended to consult a professional or refer to a specialized repair manual for more specific and detailed instructions.
