My main takeaway was that this adhesive is meant for structural use, especially where I need a reliable bond between panels, trim, or similar surfaces.
What I Look For Before Buying
Before I buy this adhesive, I always check a few important things:
- Whether I need a structural panel adhesive or just a general-purpose glue
- If the surfaces I am bonding are compatible with the product
- How much working time I will have before it cures
