Hey Bud, I got the Rev4 L2 ATS today. The screen was definitely dried out but didn't seem to be cracking or anything. I have it soaking in a bowl of tap water now. Wanted to start a thread so that this is documented in case anyone else has this issue. I am hoping to not have to re-mortar it if I don't have to. How long do you think I need to soak it for? How do you think I will know if it was successfully "rehydrated"? Thanks!
