Hi guys, I have a question to ask. If a spot underneath the fender is starting to rust up and somewhat ing... you think that it will stop ing if rust proof was sprayed over it? I'm not talking about the rust proof spray you can buy at canadian tires, i'm talking about the nice and thick one from dealerships?
Yea i know that there may be a chance that the rust will still but if the rust proof blocks out any moisture from rust spots, will it still continue to rust?
I was just wondering if this will work that's all. Any help would be great.

thanks

rustproof will not stop rust but would slow it down greatly, other option could be that electronic rust control thingy it works also

The best bet is to fix it now before it gets out of hand.
