Ever Seen Rust in the bed?

oh the suspense

 

I second this guess. You can get metal contaminants that will get imbedded into the composite material and rust. You can get them just from driving around. Some people get the same thing on their paint.

You can buy sprays that neutralize rust (usually come as a form of wheel cleaner) and turn purple in the presence of rust. You can try using something like that to clean it off.

 

Is it even chemically possible for the composite to rust? I was under the impression that it is not.

 

I have rust on my bed that came from T slot mounted on the rails.

 

boom! Just noticed I didnt remove my tslots after we got back from our trip. Let the dumbass flooooow!

 

And No, composite CAN'T rust, any more then Styrofoam, vinyl, or rubber can.

 

Yup ....

 

Plastic can't rust.

If rust has gotten into the pores of the plastic and "stained" it you could try using an acid to remove it. This is how we remove rust/iron stains from pool and spa surfaces. Keep in mind you don't want to damage your bed either!!

 

Unless it has iron mixed in the plastic...a big NOPE. Just like aluminum cant rust...it corrodes.

 

Technically, rust is electrochemical corrosion.

 

BOOM! Head shot.

 

No iron = no iron oxide.

No.

 

I had a rusty bike in my bed that did the same thing. The rust stain was like embedded in the bed. Took it to the car wash and power washed and scrubbed most of it out.

 

Its not plastic.

Its fiberglass.

 

There were some metal shavings in my bed, and the next day they were rusted and left little marks like that. Maybe that could be it?

Edit: just finished reading the thread. Whooooops.

 

If there was a plastic capable of rusting, Toyota would find it and use it extensively.

 

It is actually both plastic and fiberglass. Hence the term "composite", meaning composed of multiple materials.
