This picture makes me angry. You all know how sickening it is to spend a fortune on your pool build and then have quality issues. We put our pool in 2017. The weight of concrete seems to have been made our track for the auto cover a bit unlevel in certain areas. Anyway, time for new stain so ignore that. However, in many areas my silicone has either fallen out, cracked, or turned black. Unsightly. And dirt or sand can come thru into the pool. I really want to take care of this. The silicon needs replaced between the auto cover and the top of the tile line. What is the best product? Some areas are small in width, others are much larger.
