This damage can take two forms:
blotchy, ringlet-shaped discolorations,
and small irregular dark spots etched
into the paint surface.
Although no defect in the paint job
causes this; Pontiac will repair, at no
charge to the owner, the surfaces of new

clearcoat" paint finish. The clearcoat
gives more depth and gloss to

colored basecoat.
