Hi Pat, We need to redo our cedar deck. After reading the comments on your experience with GacoShield, we are interested in getting a little more information. You mentioned in April that there was some cracking on one of the stairs that you did. Has that gotten any worse during the summer? Do you think that you can just add more of the product over the crack to fill it in? It is hard to find much info on the internet about personal experiences with this product. Thanks for your help.
