Dealing with a bit of rust - Zilvia.net Forums | Nissan 240SX (Silvia) and Z (Fairlady) Car Forum

I have worked on the 240sx a little bit lately. I'm nearly don removing the tar mats with only the wheel wells left to do.

I have however found a bid of rust that I will hopefully be able to deal with. I got a rusted hole were a drain plug used to be (this was under the tar mat).

I also have some rust at the front bottom of the driver's side wheel well.

I also have a couple of small holes at the drivers side trunk floor

The passengers side wheel well has rusted though at the trunk seem as well.

I noticed that a lot of the rust appear at the seems, behind the seam sealer the factory puts on. Do you guys have any tip on how to remove that sealer and get a better picture of what needs to be fixed? Any advice?

This car will be track only ad hopefully never see rain again but I'd like to fix what's there.

On the areas that were just surface rust, I just wire-wheeled the area to bare metal, used rust treatment and painted it. I also had a rusted out drain plug. I cut it out and welded a small plate in, treated it and painted. The areas that were on the seams were luckily just surface rust, so i wire wheeled them to bare metal, added a couple tack welds, then treated and painted. Luckily none of the seam spots were rusted through.

Not sure if it was the correct way, but that's what I did.

Repairs sound good. so many of these poorly treated over the years...

Yeah. Canadian winters and road salt are not very kind to 30 year old chassis.

My seems are rusted through so some plates will be required. I have a MIG but never used it. I will also need smaller gauge wire for it.

I'm reading this thread from fellow Canadian for inspiration but good god I don't want to have to be as thorough as he was.
