The best sealant for 3 piece wheels is Dow Corning 832 sealant
Also as suggested: Urethane Windshield Sealer or Permatex Ultra Grey.

Clean the halves very wheel, torque the bolts in a sequence and then apply the sealant to the joint.

RTV Silicones that are acetoxy catalyzed, release Acetic Acid while curing and not good for Aluminum or Magnesium wheels.

As Mike Pearson stated, you need to use a light acid based cleaner to remove the residue and clean thoroughly with Acetone or MEK..
