thats the plastic thats dry rotted zipp
started sanding and doing a red neck rattle can primer job in driveway today.
just to get it one color and address the little surface rust issues ya see(yes i am taping it off. that stainless trim a pain to find by 80-81 when to plastic) Good thing is mama likes the "hot rod" primered look so she will more then likely pick paint by fall and I'll paint over the winter
