either is okay,but a generic pu sealer is what i generally use,as it is half the price
of sika or 3m products and just as good most hardware
stores carry it as a high quality polyeurathane outdoor window frame sealer,check the label ,clean up with white spirit.
if you use liquid cement to fill the voids via the bilge
,it is a good idea to epoxy/glass over any drill holes afterwards to prevent further oil/water from entering the keel ,or exiting!
