2005 Nissan Altima Q&A
2005 Nissan Altima Question: Does a rusty undercarraige get better with time?
once the car is rusted it is rusted the only way to stop it from rusting is have it sandlasted and undercoated - goodguy
you will never solve this problem. you will have it forever,you may slow it down but thats it - globalhelper
Rusty undercarriages will either get worse or stay the same...it is impossible to improve on its own...isn't Florida a humid state? Humidity causes rust so even while warm it is still not dry. - your.mechanic
