I went through the problem that no matter what I used, there was nothing that worked for me. It wasn’t until I was diving with one of our divebuddy members that he told me to just swish it around in the water after letting the SEA GOLD dry. Here I was putting the stuff on then letting it dry and wiping it off. I guess I took the directions too seriously. But now that I know how to properly use it, I can do 1 application and it will last the entire day. Thanks Dave!
