[email protected] Posted November 13, 2017 Report Share Posted November 13, 2017 I am planning to Rustseal and then undercoat the underside of my Impala using the three step process,. If I need to grind down to bare metal to weld on an exhaust hanger, for example, can I touch up the exposed area by applying Rustseal and then rubberized undercoating to the bare metal? Will this be effective in preventing rust? Quote Link to comment Share on other sites More sharing options...
