Hi, We applied Amberseal today (it's quite remarkable and easy to use), however we ended up with an irregularity between two sections. It's basically a line between one section and another. What are our options? Sanding it out? Adding additional Amberseal on the lighter area? Any advice you can provide would be much appreciated. Thanks!

Adding more amber seal would be the easiest. Blend it in before the first coat has completely cured.
