Coatings

The interior was primed with Corroless EPF and finished with Corroless RF35 (2006).
The exterior, with the exception of the roof, was spot primed with a Corroless S1, followed by a full coat of Corroless SHB and finished with a coat of Corroless RF16 topcoat
The exterior roof and the base of the legs was treated using two coats of Corroless EPF.
