Before I found out about it, I used to send my mom pics from my iPad and she would always say " that's nice , but it's upside down" then my young working buddy ( who totes an iPhone ) told me about holding it with the home button to the right. Glad you got it fixed @jscarfo.
I put one on my large about 4 months ago and it still looks new. I have had a couple of 750 degree cooks and it hasn't phased it a bit! I am we'll pleased with BGE new high temp. Gasket, and I know you will be too!
You can buy some zinc spray( looks like a bottle of spray paint) and spray the edges then let dry then put your plastic cover over that. I do electrical work and we spray all galvanized metal on the edges where we cut and it works great to prevent rust. Good luck!
