mallorybl Posted June 26, 2009 Report Share Posted June 26, 2009 I intend to cover the underside of my newly installed galvanized floorboards w/ Herculiner. The rest of the undercarriage will be coated w/ KBS rust seal then the herculiner. Should I use the rust seal over the floorboards as well? I intend to sandblast the rest of the undercarriage. Should I do the same to "etch" the galvanized steel? Or, how would I get the best results? Quote Link to comment Share on other sites More sharing options...
