What I Look for Before Buying
When I shop for a Devcon product, I first think about what I need to repair. I look at the material, the size of the damage, and whether I need a quick fix or a long-lasting bond. For me, the right choice depends on the surface I’m working with, such as metal, plastic, wood, or concrete.
