This will be my first year spending a winter up in the "salt belt." Since I moved up here, I have noticed lots of cars all rusted out. I'd like to take care of mine the best way possible, and I'm worried about underneath. Does undercoating actually help protect the bottom of the car?
I see several products at my local auto parts store, and there's a shop nearby where I can pay them to throw it up onto a lift and let me spray away, but I don't want to waste my time or money if they're not effective. What do you all think?
