Those stains are not from Hyperdressing. Think about it. Slinging happens with movement, so how would a thin, water-based dressing that is almost fully absorbed into the rubber with very little residue left on top, leave large blobs on the paint while the car is moving? It wouldn`t. Even if large amounts of dressing were hiding in the tread edges by your sidewall, they wouldn`t sling and sit in large drops on the panels when the car is moving. When HD slings, it leaves thin, long (and almost black) smears on the paint created by air moving around the car.
You likely drove through something thick and sticky that isn`t affected by air, like tar or low viscosity oil. I was also thinking perhaps someone emptied out a container of some liquid near your parking spot, but that wouldn`t affect both sides of the car.
To rule out tar, try WD40. It works wonders on that. IronX is only for iron deposits; I struggle to think how iron deposits of that size could show up on a moving car.
For tires` ages, I am surprised no one has mentioned checking the date stamp on the sidewalls as required by law. Each tire is stamped with a 4-digit date code on the side, with the first two numbers designating the week and the second two, the year of manufacture. e.g. 1817 would mean the 18th week of 2017, or sometime in May 2017. Each tire will be different unless they are all from the same batch, so look at each. The code is close to the DOT registration stamp that`s also on the sidewall (starts with `DOT`). That fact that your tire shop had to special-order these has little bearing on their age. Tires sometimes sit in the warehouse for years, even for a high turnover franchise.
Sorry to see this happen. Keep us posted on what you find out.
