Rust Advice - S2000 Sills

[Badgerboy]

Chaps,

Just started noticing this coming through on my S2000, and hoped I could get some suggestions on how to deal with it?



(The discolouration is simply where I have wiped the dirt away on the sill)

The car has has a replacement rear quarter at some point in its life, just not done that well. The rust bubbles are very minor, but I'm more concerned of it spreading along the seam. For the moment I was thinking of;

1. Rubbing down the raised bubbles, and clearing out the seam.
2. Assess the quantity of rust, and cut/sand out as required.
3. Treat with some form of anti-rust product.
4. Touch up treated spots until 'Chips away' chap can do a quick spray repair.

Any thoughts on checking on inside the sill? This is pretty much my main concern. It ideally needs a new panel, but I won't be entertaining that until I get the car completely repainted.

Thanks

Nice splodge job..

I would wirecup brush it back to bare metal. Rust treat using Bilt Hamber Hydrate 80 which will creep in the seam to make it watertight and hopefully neutralise any corrosion between the join. Seam seal the non-visible part. Then prime and paint. Not a 5 minute job.

I can see filler in both panels from the old repair ,so that will be opening up a can of worms once you start .

Thats a case of leave it or it will get worse or get it fixed properly at bodyshop .

The filler is hiding ground down plug welds from a mig, you can just make out the circular under the filler on the left side of the seam. To fix what is a cosmetic issue by cutting the panel off and refitting is hugely expensive and time consuming. My advice would prevent any further rusting to the seam, it would take years for it to become a structual issue, so my advice is don't dig too deep unless your pockets are equally as deep.
