Volkswagen Golf Service & Repair Manual: 1-pack anti-corrosion wash primer

Designation:

1-pack anti-corrosion wash primer -ALN 002 003 10-

Issued 06/2011

Product description

1-pack anti-corrosion primer is a zinc chromate-free one-pack product based on polyvinyl butyral for passenger car refinishing. The special combination of pigments and binders provides good corrosion protection and adhesion and is also certified suitable for application on welded joints. However, because this product is non-conductive, it is not suitable for use with spot-weld work. It is recommended to apply a coat of 2-pack HS surfacer over the 1-pack anti-corrosion wash primer -ALN 002 003 10- at remaining rust spots on corners and edges, as well as areas which have been sanded bare.
