The Vintage Fiberglass Repair Kit by 3M is a retro advertising collectible that offers a unique solution for repairing metal, wood, and fiberglass surfaces. Made in Minnesota. With its classic design and reliable brand, this product is a must-have for vintage enthusiasts and DIY collectors looking to preserve and restore historical or retro objects. Not sure if the product is still useable. This would look so cool framed on a wall or hung as is in a shop area or mancave. See photos - package has some damage, but in good shape for its age. Unsure of age, but that logo version was used by 3M in the 60’s/70’s.
