Understanding the Trade-Offs
Each Sealant has its strengths and limitations. Consider these factors 
when choosing:
• Desired Lifespan: How long do your units need to last?
• Climate: Will they face extreme temperature or UV exposure?
• Budget: How does material cost factor into your project?
• Installation: Do you need fast cure or specific application methods?
