ON A 69 CAMARO INSIDE THE TRUNK AERA WAS THE UNDERCOATING SPRAYED ON THE QUARTER PANEL FIRDT THEN SPRAYED WITH THE SPLATER PAINT OR THE OTHER WAY AROUND
That thick coating was a sound deadener (it helped prevented the panel from oscillating) and it was sprayed first, then the spatter over it.
Mike
great thanks
from what I can tell from my original car...
