How bad is my boot? Be honest

brake cleaner/thinners and rags should get the rest

Thank you! Would Kerosene work by any chance? It’s just that that’s what I already have at home …

No idea, I don't have any around. But a quick search says it is no good for the paint's clear coat so probably not a good choice

I'm not sure why you removed the sound deadener??? 

Don't bother with DIY remedies... this is how you can do it properly.

For the lightly stained areas, just stick to a fine grade wet sand paper....and then paint over once the stain is gone.

For the worst areas...especially the pitted ones...you just need to sand the rust in the localised spot working down from a heavier grit to medium grit wet sandpaper, which will get most of the rust off. It's just localised rust from the spare wheel touching the boot. Don't go to town on sanding the whole boot...not needed! Try to avoid sanding the seam sealer etc (obviously)

After the rust spots are down to bare metal - use a fine brush dipped in "RUST DEOXIDISER"...and carefully apply this to the little rust areas. It's important the chemical you use is DEOXIDISER.

After applying that, let it sit for a while and obviously wipe off with prepsol before it dries, and repeat 3-4 times. If you go to a panel shop they will probably be able to sell you some - as the trade products are a shitload stronger than retail products.

After deoxidising the rust, scuff the surrounding paint with red scotch brite....& then you are ready to apply etch primer and then paint the matte gray colour on. Mask up the surrounding area using tape & paper..... as you don't need to paint the whole boot, just blend it in and keep the repair as small as possible. Spray can paint or spray gun depending on your level of expertise will be fine.

Probably will cost you about $100-$150 in materials.

Kerosene and an old toothbrush worked great on most of the spots. I tried the wire sponge on the stubborn spots but they wouldn’t budge.

By the way, how do I remove these plastic clips in the boot? The arrow points up so I tried it with the arrows pointing down (and up) but I just can’t get it to move

Try various orientations until it releases? I don't recall having any issues with those clips.

You may need to put something between the two pieces of trim to prise them apart while you turn the clip. There's no science here. They are very simple, just a little annoying sometimes.

Prise them apart with arrows pointing up or down? 😬

Got it 👍

I was going to pay someone to finish it all off. But after being quoted $700+ I’ll just follow your recommended steps and try and deal with it myself. Thanks again!!!

Remove the sound deadener with dry ice; wire wheel the rust marks; paint with kbs; reinstate the seam sealer; cover with new sound deadener

Will this wire wheel kit do ok? https://www.bunnings.com.au/josco-3-piece-drill-brush-kit_p6111235?store=5228
 

I’ve removed the carpet lining from the boot. Is there anything else I need to keep in mind so as not to cause any damage?

[sonic99]

I’ve reached a point where I’m beginning to think I should have just left it as it was… so the question is… do I abort mission or keep going? Should I aim to remove all the discoloured spots around sealant also? How long is a piece of string?

This is where I’m at now 

[sonic99]

I did a bit more cleaning and this is where I’m at now…

I’ve concluded that the sealant parts that are discoloured aren’t necessarily rusty 😵‍💫

However, the parts circled red are rusty but I’m finding it difficult to get to them. Especially the only on top and the one next to the rubber seal down the bottom. Any tips on how and where to from here?

[tridentt150v]

Remove any flake or loose rust with said wire brush.  Get a rust sealer like Septone and convert/seal the rust.  Use a quality primer and paint over the Septone areas.  Lastly paint the whole boot area, several coats, sanding lightly between dry coats.

This should take care of all the rust, boot paint quality, and your time for the next few months.

700 buck quote is looking pretty good!

I just did this on my hydraulic tank and subframe for a dumper.  The battery is right next to the tank and [from previous owners] acid spilled out and ate the tank away until I lost hydraulic fluid...so I took the tank out, cut the rust affected part out and replated...then I used a wire corded type brush on an angle grinder and got the rust off the subframe and the rest of the tank.  Then did the above steps in my previous posts.  With waiting for the prep/primer/paint to dry between coats etc it took me around 10-12 days...hot sunny days.  TBH I should have done it before, but 'if it ain't broke don't fix it' + laziness took over :).

 

[sonic99]

Thank you, all. I wish I could go back in time 😢

I took a photo of the undercarriage and it looks like the boot has rusted all the way through. Is this correct? 

[tridentt150v]

Nah, looks like surface rust to me.....the outer skin lives in a hostile environment.  You might have to consider 'de-rusting' this area as well?

[GTSBoy]

There's nothing wrong with the car at all. That rust is nothing.

Hang the halo on the bedpost and drive the car. Or completely strip it and factory rebirth it for $200k. Anything in between is almost certainly a waste of time and resources.

[tridentt150v]

Gotta admit, I'm [like many others on here] sitting here scratching my head wondering what your doing and why.  The 'rust' you are having sleepless nights over is nothing.  Personally I think you have made a mountain of work for yourself.  Close the boot, open the bonnet and do work there.....thats where the go fast stuff lives!!!!

If you must, ,,,for that 'rust' under the car, coat it with Septone converter, then use an undertray primer/bitumen type paint and forget it.
