I believe that you may find that there is no sealer used on the AC (I could be wrong). The AC units are usually installed with a thick foam compression gasket.
For the vents, a good quality silicone sealer works great. If you use something like 3M 5200, it will do a better, longer lasting job of sealing but if you need to replace the vent for any reason, you will find it extremely difficult (to impossible) to remove without damaging the roof.
After removing the vents, achieving a perfectly clean srface is critical. Use an ample amount of sealer on the vent so that when you screw it down, sealer oozes out of every side. Clean-up immediately with mineral spirits (some sealers only require water for clean-up).
