Need an undercarriage protection for our 2003 chevy blazer - cant find one!
There are any number of commercial protection products available over the counter.. of any auto part store, or online.
In my own humble opinion... Your best protection is regular washing with clean water, and some WD40 on all unpainted surfaces. Any coating you put on will eventually trap moisture and contaminants under it, causing corrosion faster.
Easy way to prevent undercarriage rust is to power wash the entire undercarrage, then spray the entire undercarriage with WD-40 before the onset of winter.
WD-40 displaces water, helping to keep rust under control. Suprisingly, it doesn't come off as easily as you'd think in wet winter driving.
Use use two medium size cans of WD-40 to do all undercarriage, making sure to spray every nook and cranny (but avoiding the brake rotors/pads) until it is saturated.
Believe it or not, one good coating will last all winter--at least enough to prevent rust. Each spring, use a high pressure sprayer to clean the undercarriage and reapply a new coat of WD-40 for the spring/summer/fall months.
