Seeing that "over ten years" bit really hits home. I've seen so many quick fixes fail after a couple seasons, it's frustrating. Solid methods like that silicone stuff making the rounds is a total game changer for quality work. Honestly, it's about time we focus on stuff that lasts instead of cutting corners. Makes all the difference for clients and our rep.
In a trade magazine last month, I read about silicone-based sealants. The article said they can last over ten years with correct application. Seeing your update makes me glad those methods are catching on.
