Ok, so heres the deal. I have been researching how to care/treat/prevent rust. What I have found is there are a TON of methods how to treat them. Some of them are band-aids, some of them will work for a while and others are full proof(for the most part) Now I understand there is more than one way to skin a cat.

Can someone guide me in the right direction on how to PROPERLY treat rust? This is in reference to a quarter size rust bubble on my truck floor pan. I know that what is visible is 1/3 of the damage until you expose it more. I'm looking for a step by step process to rid, treat, repair, paint. The truck has barely any rust and I want to stop it now before it gets worse.
