Originally stainless steel, the Sweepspear eventually became a vinyl rub strip or simple character line in the sheetmetal, as hinted in some versions of the Buick Riviera, distinct on the 1968–1969 Skylark, and appearing on the 2008 Invicta concept car. Often optional trim was available to reinforce a plain character line in the bodywork.
