| My 04 MDX has many rust spots on the bottom part of doors. What is the best way to remove the rust. I used hard sponge before, which cause lots of fine scratches. |

| If it's just staining, use 3M Microfinishing glaze or chrome polish. |

Where exactly on the doors is this rust? This makes a big difference on how you treat it.

Obviously if it's rusting that means there is bare metal. The only way to remove is is to sand it out, which you should then coat it with something and then paint.

Two steps. Naval Jelly, and primer.
Stupid name, but brilliant product available at any hardware store. Primer, because it only rusts if bare metal is showing, and it will rust again if you don't use a rust primer. A little rust coating inside the doors won't hurt either.

| Do you sand the rust then put naval jelly over? Or do you put the naval jelly over the rust? |

| I have the same issue with my black MDX. Two spots on the driver side on the door edges. You would think the metal would be exposed and started rusting but it looks like it's coming through the paint and clearcoat. I'll take some pics over the weekend and post them. |

naval jelly is applied first directly on the rust, and will eventually dissolve the rust deposit...just remove residue, and then sand to bare metal. Wipe it down once more with naval jelly, dry, and prime.
As per the name, it's used by the navy on their ships to stop the salt water from rusting it away. also used by body shops. It's a pink gelatin form of acid. It will eat through paint as well as rust, if not wiped up. Strong stuff.

I suspect water has gotten into the inside of the door frame. It's eating its way from inside the door to the outside. Inject "Rust Check" into the doorframe interior to stop the rust inside, and then treat the outside.
This is usually an ongoing battle to stop it dead, but you can eventually win if you keep rust-checking the door panels in and out. Good luck!

| I was reading this thread and thought I'd put my two cents in. This spring I noticed a LOT of tiny "rust" spots on the lower panels of my '04 X. I thought the winter took it's toll on the body and I was in for some serious repairing. Turns out my neighbor saw me trying to get these spots out and he said it was "rail dust". He brought over some Mothers brand detailer spray and a clay bar. After putting on the spray for a lubricant, the clay bar took the spots right off. I could have sworn it was rust but it looks better than new now. I hope this helps someone out there. |

| BisMDX is right. Most of the rust is not 'real' rust. They are "rail rust". I tried clay bar too. It removed most of the "rail rust", but some of the "rail rust" were too tough to remove. What is my next option? Any paint cleaner I should try? |
