Acrylic tubs bond very differently from porcelain. They require an adhesion promoter specifically formulated for plastics, plus a bond-coat cycle before the topcoat.
Done correctly, an acrylic refinish lasts 10+ years with the same premium urethane topcoat used on porcelain.
Skipping the specialized bond coat is the #1 reason acrylic refinishes peel — always ask your refinisher which primer they use.
