How did you deal with rust?

I have a 2008 Yukon Denali that I purchased about 6 months ago. I've noticed there is rust forming on the bottom of the hatch and the bottom-rear of the back doors. I can see why since the back edge of the door is basically the edge of the wheel well unlike if it was an XL. What have you done to remedy this and help prevent it from getting worse?

Rust needs to be stripped off entirely and repainted. Once the rust is removed and repainted that door skin lip can be sealed better with a can on duplicolor shaker can bedliner or plastidip. Any place where water can sit will tend to rust unless its sealed or cleaned in a regular fashion.

That's minimal amount of surface rust that you have compared to what my 2007 Tahoe had and still has. Unfortunately my car came from the rust belt (northern Ohio) and had a roughly 6" rust spot on the edge of the left rear door. A very small area on the right rear door and front part of the hood. I live in VA and took it to the nearby body shops. Most didn't want to touch it as they can't guarantee rust work, and some wanted to start replacing panels which didn't sound like a good idea to me since it would cost me over a third of what I paid for the Tahoe.

I eventually took to a nearby MAACO and they agreed to fix it for me. I had them fix the worst spot as I didn't want to tackle it myself. Paid $300 for it and it's been about 7m now since they repaired it. I can tell small bubbles are coming back under the paint, but I think overall it's worth fixing it even if I have to take it back to them in a year or two.

Smaller spots I tackled myself. They were a bit worse than what yours look like. I order my color kit from here: http://www.automotivetouchup.com/

It was a perfect match for my gray color. I ordered the spray can kit. Comes with primer, base and clear coat plus sand paper for about $50. I also ended up buying a can of bondo.

If you do tackle it yourself, take your time while doing the repair. Follow it step by step and have patience. I didn't do that and it showed in the quality of my work unfortunately.

Hope this helps.

I was cleaning my truck today and noticed some rust on the lower corner of my driver door so i took the rubber part to find...
I think the best way is to sand blast it and repaint the inner part

Also check your drains in the doors. They are notorious for clogging and allowing water to sit in the door pockets, thus causing that rust.

Old thread I know, but for the archive... spray Fluid Film on the inside of each hole where the rubber strip connects using the straw that comes with the product and also spray it on all the visible rust on the outside of the lower door. Clean out the drain hole. Do this once a year and it will most likely keep it from progressing. I'm on year 3 and it looks no worse than the day I discovered it on all doors and lift gate in the same spots as depicted above. Fluid Film is amazing. Search it on Amazon.
