TundraGeneral discussion forum for the 2007 and later Toyota Tundra.
This is a discussion thread titled "Rust already front and rear bumper", within the Tundra forum, part of the Truck Forums category.
I was washing my truck yesterday and noticed that I have rust around the fog lights. I also noticed rust on the bumper under the fender. You can't see it unless you look under where the fender and bumper come together. 5000 miles and rusting already...next service I will show the dealership. Rear bumper has rust spots.....
ya mine around the fog lights starting to show discoloration. I took it to the dealer and the service manager told me that's just the way it goes up here and I should take the bumper of in the spring and polish it out. I think that's bull**** and I shouldn't have to take out my foglights and all that jive after 6 months. Also the center cap on one of my wheels the trd ones started to peel like the clearcoat or something. They replaced it immediatly. If it gets any worse I'll talk to the dealership owner or something.

I had surface rust on my rear bumper. This past weekend, I used "Nevr Dull" on it and the rust came right off. The bumper is nice and shiny like a mirror again.
I think that chrome is just one of those higher maintenance type metals. Any chrome I've ever had ended up with surface rust that requires regular polishing. Firefighters polish the chrome on their firetrucks and bikers polish the chrome on their bikes. As long as you keep on top of it, its fine.

Except typically if you have rust, that means there is no chrome there. There is exposed steel which rusts when exposed to a corrosive atmosphere. I have a 30 year background in metal finishing and I can tell you that Chromium does not rust. It is the steel underneath that rusts.
How does this happen? Typically from a poor preplate cleaning cycle or inadequate thickness of the underplate. We can probably rule out poor cleaning because that usually manifests itself with blistering, peeling and flaking of the plating. Likely, Toyota or whoever the supplier was that plated the bumpers did not provide sufficent underplating. Sometimes this is a combination of copper and nickel, but in the automotive industry today, typically they use 2 layers of nickel and then chrome. Most decorative chrome is 10-20 microinches thick (10-20 millionths of an inch) and it is very hard and durable, but it is the underplate that gives it a lot of corrosion resistance.
In my opinion, The fact that it is happening around the foglight cutouts further bolsters this theory. Practically speaking, this area would receive less plating because it is what is known as a "low current" area and does not plate as much as the outer edges.
Toyota should fix their process and do corrosion testing (salt spray per ASTM B 117) on their chrome plating process and prove that the process can meet industry accepted standards for corrosion resistance.
I live in Maine and we do not spare the salt on the roads. I wash my truck once a week, but I have the rust forming in this area as well. I haven't really decided what to do about it.
Hello everyone, I'm new to this forum. Hearing of the surface rust on areas of some of your bumpers. Well I have 20 years working in Autobody, and what I see is that it is not only the Tundra with this problem, but most of the other brands of trucks as well. Most of the plated bumpers have very thin coverage on the rear, edges and openings and these areas start to rust in a short period of time. I see trucks 2 and 3 years old with large areas of rust behind the bumpers. Spraying a petroleum based rustprofing on the back of the bumpers is one way of putting a protective coating on them.
I have the rear sonar sensors and the rust is just pouring out of the 4 plugs. The truck is 3 months old. To say I'm pissed is an understatment. The dealer was to put in a rear camera and put the sensors in by accident. Going to stop by the dealer this weekend and try to get this resolved. Haven't got my new car satisfaction survey from Toyota yet... the dealer will tip the scales one way or the other in a few days.

I had this done yesterday at the body shop that replaced the side of my bed. Its like a very sticky oil. They sprayed all behind the bumper and said it helps with chrome bumpers to prevent rusting.
