Working With Aluminum
Repairing aluminum body panels can be quite different than repairing steel.
Aluminum Repair Resources
When working on aluminum, it’s best to have the latest information. That’s where Toyota’s Technical Information System (TIS) comes in handy. Go on TIS and enter the specific information for the vehicle you’re repairing and look under the Collision Repair folder.
Aluminum and Automobiles
Aluminum and steel are two distinctly different metals. Here’s a chart to help you know some of their differences.*
Repair Procedures
First and foremost, be advised that various OEMs have different rules/repair procedures when working with aluminum. Just because you’re trained or certified with a particular OEM does not mean those same considerations can cross over to another automaker. While this can be frustrating, it’s important to note this current inter-industry reality.
Different Grades
Aluminum, like steel, has different grades and characteristics that determine strength and repairability. Aluminum is graded in seven different series, so knowing what series you’re working with is important when determining repair plans and procedures.
Corrosion
When working with aluminum, things to consider during repairs are galvanic corrosion and cross contamination. It’s critical to keep steel and aluminum parts separated during a repair to avoid any particulate contact between an exposed bare metal body panel in the surrounding area.
Glue Pulling
When repairing dents on an aluminum panel, my first choice of repair method is the use of glue-on pull tabs. If this doesn’t work, I suggest using paintless dent repair (PDR) theory and methods.
Separate Tools
Along with a designated space/area, aluminum dust extractors and separate welding equipment, you must also have a separate set of hand and power tools to avoid cross contamination, including but not limited to different gloves, sandpaper, saw blades, grinders and grinding discs.
Structural Realignment
The most important topic regarding aluminum currently is structural realignment. Should any aluminum structural part on an aluminum vehicle or mixed-material structure be pulled out on a frame machine? As a trained certified aluminum structural technician, my answer to that question is unanchored pulling only, using only the weight of the vehicle.
What is 3M body repair?
3M provides technical resources to address any concern you have about working with aluminum in auto body repair. Here are some quick tips that can save you a lot of worry and hassle in the aluminum shop.

What is express repair?
Express repairs, or removing minor dents and dings from aluminum panels where paint hasn’t been compromised, are increasingly common in the body shop. These 3M SOPs detail the procedure for repairing small aluminum damage areas.
Does aluminum peel?
Technical Tip: Aluminum naturally forms a very thin layer of oxide on its surface. This layer (normally just a few hundredths of a millimeter thick) tends to impede the adhesion of coatings, such as seam sealers, fillers and primers, and can cause them to peel.
Can 3M be used for aluminum?
With very few exceptions, all 3M materials that are used for steel repairs can be used for aluminum repairs, as long as they are used in accordance with directions for use, OEM guidelines and 3M standard operating procedures for aluminum substrates.
Can you use 3M seam sealer on aluminum?
Good news: the same commonly accepted repair practices and products you use for steel – including 3M seam sealers, body fillers, undercoats and abrasives – generally work very well for aluminum auto body repair. That said, it’s important to follow some critical guidelines for repairing aluminum in the body shop.
Why is aluminum reshaped?
An aluminum panel that has been reshaped due to collision forces will take on a new shape and forget the old shape. The next factor is that when this reshaping occurs, the aluminum panel will also undergo some work hardening. Work hardening is strengthening through shaping.
What to use to straighten a dent?
With areas of limited access to the backside, using a weld-on dent puller for straightening is also quite common.

Can you repair a steel door with a crease?
When considering these factors, the size of the damage becomes a consideration. A repair that can be done on a steel door with a large crease may not be feasible on an aluminum door with similar damage. Location is another consideration. Small damage with backside access may be quite easily repaired on an aluminum panel.
Can you use weld on dent pulling on aluminum?
Weld-on dent pulling equipment used for steel panels will not work for aluminum panels. There are aluminum-specific weld-on dent pulling tools available from some equipment makers. There are also glue-on and suction cup types of dent pulling tools available.
How does heat affect aluminum?
Heat is often used to soften the aluminum to reform the panel. The use of heat must be regulated so as not to destroy the aluminum. We also need to make sure where and how far the heat regulates outward. The heat can weaken or separate adhesive joints and foams, which will create even more problems to repair.
Is aluminum a strong material?
Aluminum is very strong and, when a panel is damaged, it’s formed to the damage. This work hardens the aluminum, making it really strong. Repairing the damage without damaging surrounding metal can be difficult. Heat is often used to soften the aluminum to reform the panel.
Is aluminum repair a time consuming process?
Dilemmas. One of the first dilemmas that many face is that aluminum repair or removing a dent is a time-consuming process. It’s not the same amount of time as a steel dent and is more labor intensive. Aluminum is very strong and, when a panel is damaged, it’s formed to the damage.
