Key Primer is a waterborne primer for non-ferrous metals, fiberglass, and plastics. It is an appropriate primer for use under Eco or Eurolux paint, but if Hollandlac is the desired topcoat (i.e. you are painting a fiberglass door) then Key Primer must be reprimed with FPE Oil Primer before Hollandlac can be applied.

👍 We recommend Key Primer as a basecoat on hard-to-stick-to surfaces.
