@southcoastsealantsltd: The new Arbo external silicone has had a serious upgrade. The biggest improvement is the much longer skinning time, giving you around 25 to 45 minutes to gun your joints before tooling. That means fewer wrinkles, no rushing, and far fewer joins on long runs for a much cleaner finish. It's also got excellent movement capability, so it's ideal for external joints that expand and contract with the weather. The new consistency makes it smooth to gun out and really easy to tool, even on hot days. Arbo has also updated the formula from Oxime to Alkoxy and given it a fresh new cartridge design. Overall, it's a much more user friendly product that makes achieving a professional finish even easier.
