These heavy duty truck technical tips are just a small sample of our specialized knowledge in commercial vehicle repair. Our technical team is here to help meet your technical challenges in the repair of heavy duty trucks.
Customer Challenge: Much of our work on heavy truck collision repair involves composite panels. What should we be most aware of to ensure effective panel removal and installation?
Technical Tip: It’s important to know that SMC/FRP panels should be cleaned only at the beginning of the repair process. Cleaners should not be applied after the initial cleaning through the rest of the repair. If you use flame heat to help separate composite panels, you must remove the afterburn with a P80 abrasive. If you are using an adhesive such as 3M™ SMC/FRP Repair Adhesive and you need to adjust the panel during installation adjust it by sliding the panel to avoid causing air bubbles in the adhesive. Finally, do not over clamp during part mating, as this can result in too much squeeze-out and can reduce the strength of the bondline.
Customer Challenge: As a 3M distributor, will I need to update my 3M product selection for heavy duty truck repair accounts?
Technical Tip: The main differences between truck repair and repairing smaller vehicles are the size of the vehicle and the higher frequency of composite panel materials. Heavy truck repairs require many of the same sealers, cavity waxes, metalworking and aluminum repair products as the smaller vehicles many shops work on every day. Therefore, you should not need to make major changes to your product mixes, though you may require larger amounts.
Customer Challenge: What are the advantages of using bonding adhesive in conjunction with metal mechanical fasteners on large truck panels?
Technical Tip: In most cases, bonding adhesives can be used with rivets or other mechanical fasteners to enhance the strength of the bond between metal parts. (You should always use a bonding adhesive if it is specified by the vehicle OEM.) When the addition of an adhesive bond is not required, a high-quality bonding adhesive can also be very useful as an isolator when working with dissimilar metal panels and fasteners during heavy duty truck repair. This involves simply applying the adhesive to bare metal on mating flanges and allowing it to cure. The adhesive can also be applied to drilled holes where dissimilar metals and rivets come into contact to help prevent galvanic corrosion.
