No heat or burn damage when additional welding is notrequiredCorrosion protectionCan act as a sealantImproved process for complicated shapes (wheelhousearea)The General Motors specification for metal bonding adhesivesis GM-6449G. The scope of this specification is intendedto provide the performance guidelines of structural adhesivesystems used to repair (metallic) automotive bodies in theaftermarket.
