NOVOL PROTECT 310 Acrylic Filler Primer 4+1 HS P3 Grey

NOVOL PROTECT 310 Acrylic Filler Primer 4+1 HS

NOVOL PROTECT 310 is an acrylic resin-based, high-build 4+1 HS filler primer developed for body repair and paint preparation work. Thanks to its high spray viscosity, it can also be applied in thick layers, making it especially suitable for correcting larger scratches, sanding marks and surface irregularities.

The product provides very good adhesion to various substrates, is easy to sand and creates a stable base for subsequent paint layers. Thanks to high-quality resins and special additives, it provides good corrosion protection and isolates polyester materials, such as body fillers, from topcoats.

PROTECT 310 is available in three colours: white, grey and black. By mixing the white and black versions, different grey shades can be produced, allowing the repair to be better matched to the topcoat colour.
