First, if using a hair dryer, what setting should that be operated at? It would be much cooler than the heat gun, right?
Second, the iFixit basic set comes with a small, clear suction cup. Would that be sufficient for this project, or does it require the stronger pull of the other cups?
Finally, must I reapply adhesive to the case when replacing the glass? Does the original remain tacky and re-bond on assembly?
