This is up under my trunk deck lid, the two layer panel below the rear glass. I noticed some surface rust inside the panel, you can see inside the cutout. and a few other random spots around the underside of the deck and hinges. Ive noticed in the past the inner trunk area would occasionally "sweat" and have a layer of moisture on it. (This was before new seals)The rear glass channel had about 3 very small pin holes before the car was painted and the glass did leak slightly years ago but have been sealed and is dry. The car is solid and rust free other than this. Just wondering how you think i could protect this area from getting worse? There is no weak metal. Its surface but dont want it to grow into a nightmare. Sent from my LG-H811 using Tapatalk
What about coating it? Obviously removing the surface rust is not practical but should i at least coat everything with something specific? The whole trunk is still unfinished so its pretty much fair game still Sent from my LG-H811 using Tapatalk
Hahah well put. I need to at least finish up the trunk anyways. Cars painted, interiors almost complete, cant open up the trunk and see a mess now, maybe ill just shoot it with an epoxy prime before final coat or something and not worry about trying to remove it all. Just wondered what others thought. Sent from my LG-H811 using Tapatalk
You could go at it with a wire wheel on the end of a drill and then spray/coat it with a product that converts the red iron oxide (Fe[SUB]3[/SUB]O[SUB]4[/SUB]) into black iron sesquioxide (Fe[SUB]2[/SUB]O[SUB]3[/SUB]), and then prime and paint it so that it doesn't corrode any further. Better than letting the cancer continue to eat its way into your car. ou:
That will be fun laying in the trunk and having rust dust cloud all over. I'll wear my full face gas mask for sure lol. Assuming theres a brush on version of the rust converter to get into the cracks and crevices. I'll look into that. Thanks Sent from my LG-H811 using Tapatalk
I would spay it with Metal Ready. Then coat it with Eastwood Rust Encaposulator if you are worried about it spreading.
You couldn't reach all the areas anyway, and if in a controlled environment it won't do anything more for a LONG time, rust doesn't grow without moisture. If you were to cover it up without proper prep it won't be able to breathe and that will only accelerate any issue
Sand by hand 220 Spend about 20 hrs. Just hit rusty spots 150. Your skin will pull away from your finger nails. Ouch! And mix up gray 2 part epoxy. Took me weeks to get my rust gone! Rewarding when done right.
Since it is nearly impossible to paint with spray gun upside down! Buy one of those aerosol glass bottle sprayers from Auto paint store
That rust is typical. It is on every car I have ever seen including my rust free California GSX, leave it like Jason says.
Some good ideas here thanks, also very mixed opinions. So say i take the easy road, leave it and let it "breath". How would I go about finishing my trunk otherwise? Just paint everything else and leave that upper portion bare and dry? I guess you cant really see it anyways unless you're laying in my trunk lol. On the other hand I do have some 2part epoxy here and can spray it with those refillable canisters. I really dont want to spend 20 hrs in there trying to remove it all then coat. If a treatment then the epoxy is sufficient i would prefer that, otherwise if that will trap it from "breathing" and cause more of a problems later then i would just leave it bare and make sure i dont have any more people laying in my trunk and just finish off the rest of it as planned Sent from my LG-H811 using Tapatalk
Either POR15 or Rust Encapsulated following directions to the T. I like the Encapsulated because it's prep is much easier. Then topcoat with whatever you like.
I like the 'rust converter' suggestion. Just clean off the loose flakes and treat it. Wonder if a phosphoric acid treatment would work just as well. It can dissolve rust, but takes repeated applications and scrubbing. Will leave a protective coating on it. A simple soaking/spray application may provide some protection. Either method will slow down the rust process. Might be all you need.
I've just sprayed areas like that with WD-40 every so often. Easy to do and gets into all the nooks and crannies.
