For me depends on if the bowl is going to be used for food or decorative. If for food I use General Finishes Seal-A-Cell followed by Arm-R-Seal. The other finish I use is Minwax Antique oil for food bowls putting on 3 coats. I don't see any reason to put anything over the top.
The finish I use for decorative bowls is to submerge bowls in Antique oil but don't see any reason after 2 or 3 soaking coats to put any other finish over the top of this. IMHO I really don't see any benefit in doing that. I just buff and it's done.
As for lacquer I use it on small turnings such as ornaments, mini birdhouses, lidded boxes, bottle stoppers, etc.
