I've read that if your aluminum looks "sunburnt" with lighter or darker splotches it still has clearcoat, and that this must be removed if I want to polish it.
That said and taking a look at the pictures, do you think I have clearcoat still on it? Will removing it one section at a time while we polish small sections present any problems?
Any other advice?
Your description and photos indicate that you have at least some remaining PlastiCoat on your Airstream. PlastiCoat became standard across the board for Airstreams in the mid-1960s and continues in a more modern factory applied coating today. You can test for PlastiCoat with toothpaste . . . with a clean white rag, apply some toothpast and rub . . . if the rag turns black you do not have PlastiCoat in that area . . . if it does not turn black then you have PlastiCoat in that area.
Good luck with your investigation!
