The guy that's doing my floor pans recommends undercoating the entire bottom to prevent chips if I'm gonna off road it, I'm thinking about only coating the wheel wells though. Would I have issues with chips behind the front wheels on the floor pans? This would be with single stage 2k acrylic paint I just bought. I've read a little and I'm assuming an undercoated substrate would go longer before it starts rusting, but that I wouldn't easily see and repair it once it starts. So maybe paint, keeping it clean, and fluid film will be better long term? I'm young and can easily see myself having this thing 40+ years.
