If you are worried about lining it up properly before it sticks, then just use plenty of dowels as bob suggests. I put my cab on its side, with sticks/dowels every 6-8 inches. Line it up so its exactly where you want it, then remove the first dowel and work your way along it. There is is no way the dowels would stick as it must be on both sides to adhere. When done, I ran around the edge with a flush trim bit and it turned out perfect.
As a side note: To remove large pieces of laminate without it cracking from a blade or scissors, I used an angle grinder. I know it sounds wrong, but it cuts it like butter due to RPM's and there is no risk of it cracking. Handy if you need to cut out holes etc in the middle of the cab.
