If you're going for a new make, Ford holds all the power and ALL the potential to rot away. The 2004 we F250 Super Duty we just got rid of was so badly rotted (not from neglect, it was WELL taken care of), the dip stick tube broke in half from decay and rot. At that point, taking a look under the truck you could see EVERY line was about to rot off the truck. So two days later it was traded for an '08 duelly turbo diesel. Oh yeah, and that's slowly rotting away too. It's just a ford thing, dodge seems to be good with body shape, but lacks the "*****" to be a work truck. Chevs are good though, I've always been a GM man myself. Good luck though.

 

It's not Rust! Plastic doesn't rust, neither does aluminum. Those are the 2 compounds your wheels are made up of. It's your brake pads that are causing the pitting and rust looking marks. It' could also be from Wheel cleaner. If it's labeled wheel cleaner, it's harmful to your Chrome Clad, dont care much what brand it is...They ALL ARE! Degreaser is the only thing you should be using on your wheels diluted at any amount greater than 50:1. Stonger concentrations can leave stained streak marks from dripping.

Brake pads are held together by glue. As you brake, the glue melts and forms into dust particulates that burn or "etch" little marks on your wheel covers.
Wheel cleaners are meant for metals, not plastics. They all have acid in them which eats up the plastic, pits and peels them...eventually.

 

Yeah I understand that, so what do you recommend I should try to get the spots off specific name brand degreaser or should I just try some cleaner/polish and then wax after?

 

I'd use a degreaser when you wash and then a polisher after when clean.

For a current issue, the spots may come clean, but there is going to be minor pit damage left behind. Dirt will accumulate there faster now.
If your afraid of scratching the covers by scrubbing them too much, a polish is probably better to use. May not come as clean near as quick though.
