when your water smells like that when you drink it then you're the one who will wish you are dreaming. lulz
btw if you use materials such as POR 15 and coat it right you will never have to do it again but people like you choose to be cheap asses and do a have ass job sacrificing everyone elses...
you know what i mean and even thought about it before doing it. yes cars leak fluids but that's not the same as intentionally coating the underside as you are and i'm certainly no tree huger but come on man we need drinking water ya know?
most products that are labeled for undercarriage use...
i see a lot of people who post that they oil or grease their undercarriage and my opinion on that is it's terrible for the environment and also the poor bastards whom may have to drive behind you. do it right or don't do it at all.
