If you are going epoxy, it’s all about the prep work. Every garage is different, so there’s no simple way to say what prep work you’ll want, but make sure you discuss the details with your installer.
Because there are plenty of weird configs out there where people intentionally leave out things that others are shocked aren't standard. There's more than a few stripper C2's floating around. Things definitely aren't so Porsche can advertise a low starting price.
For the mass market...
