'07 Cobalt, electric power steering, 50K miles
Snow/slush/salt area. The car (new to us) hasn't had a lot of winter miles, so it's in not-too-bad condition. However, underneath today, I saw that the gas lines are showing corrosion in the usual places, near the (plastic) mounting brackets. In time, leaks will develop and I'll have to splice the lines.
Question: can I do anything now to prevent further deterioration? I imagine the factory finish is better than anything I could do with paint, etc., but maybe some sort of goo - DIY undercoat, rubber spray or roofing cement? Have people had success with anything?
