Super chippy pieces will need a coat of Tough Coat ( a water based sealer). Do not use hemp oil on these finishes as the oil may cause it to continue chipping.
If the piece chipped some, all of the loose paint has been removed and the rest is adhering well, the Furniture Wax, Antiquing Wax or White Wax will provide a wonderful finish.  The piece will not continue to chip unless exposed to intense sunlight or extreme heat.
