I use "QMAXX Salt Aerosol Spray" on areas of concern to reduce corrosion from winter salt. I've even used "Fluid film" though it's more messy.

This is the first spring in all my (lots) years of driving that has ever broke and I have always lived in winter wonderland so while there may be things that could help prevent a lot of rust, my bet is still on a defect in the mfg process.
