Best practice to attach a PEI sheet on Prusa i3 MK2

I have an original Prusa i3 MK2. The PEI sheet is damaged and I am currently removing it via the instructions in the manual.The instructions to put the new one on give me pause as it states to just take an inch or so of the adhesive sheet and then position and go from there.My hands are somewhat shaky so I am afraid I will be placing it down initially crooked and will not have any time to adjust.what can I do to make sure I have at least a few seconds to adjust the sheet before it sticks on for good?Is 90% isopropyl alcohol something I can use to reposition until, it’s right? If so, how do I go about that? Spray, dab, drip, wipe? http://ift.tt/2f9xtbA
