Temperature resistance was a key consideration, especially since I live in an area with extreme weather. I looked for adhesives that could maintain their bond in both high and low temperatures. This ensured that my repairs would hold up over time, regardless of the climate.

Compatibility with Materials

When selecting an adhesive, I had to ensure it was compatible with the materials I was working with. Whether I was bonding metal to plastic or repairing fiberglass, knowing the specific requirements of each material helped me make the right choice.

Safety and Environmental Considerations

Safety was a top priority for me when choosing automotive body panel adhesive. I made sure to check for any harmful chemicals and opted for products with low VOCs (volatile organic compounds). This not only protected my health but also minimized environmental impact.

Cost and Value

Lastly, I considered the cost versus the value of the adhesive. I found that while some products were more expensive, they often offered better performance and longevity. I made sure to weigh my options carefully to ensure I was getting the best value for my investment.
