HELP! Weird residue on exhaust
HELP! Weird residue on exhaust
No idea what it is, won't rub off, won't clean off. I have tried hot water, soap, rubbing alcohol, polish. Anyone seen this? HKS Super Turbo catback

Looks like acid-etched to me... Is it 'in' the metal (can feel the surface change with a finger nail)?
Could it be white paint? Driven on a freshly-painted street?
Try #00 steel wool next. Look up under the car too. Might be more lurking up there...
