We (Serene and I) spent like 2 hours installing the invisible shield on Friday night. Serene armed with the spray while I had my ipod and invisible shield. She sprayed the solution on the invisible shield at my command.
The corners/edges are abit tricky. Must make sure that they are not wet else it will not adhere well. It really helps if you have those silicon cases as they help to secure the invisible shield in place while it dries up.
Happy with the result! No bubbles!
