Spray Adhesives

Spray adhesives: 3M Super 77 and Maximum Strength in 7 to 14 oz, Gorilla spray adhesive in 4 and 14 oz, and E6000 translucent spray. Spray adhesive is specified by whether you need a repositionable or a permanent bond, and by whether you are spraying one surface or both. One-surface application gives a lighter, more repositionable hold; spraying both faces and letting them tack up gives the permanent, high-strength bond these are rated at. Overspray travels further than people expect, so mask well beyond the part. Check the material list before spraying foam or certain plastics, since solvent-based adhesives will melt polystyrene on contact.
