Parts prone to rust?

[power_of_dreams]

Just wondering, which if any parts are prone to rust? Are bumpers exempt because they are plastic? What about the fat structural bar behind your rear bumper?

[dc2dc2dc2]

i think anything underneath ur car is prone to rust
ie exhuast etc.

ffs, ive got a small crack in my rear bar. I worry when I go the car wash that some water is getting through and is sitting on the structural bar.

all that stuff gets wet wen u drive in wet weather. its painted neway so its not that prone to rust

Just noticed a touch of rust in a spot on my rear quarter panel just where it joins with the bumper. I patched it up with touch up paint a long time ago, but it seems rust has somehow got in. I can take off the rear bumper for ease of access.

What's the best way to clean up the rust and stop the spread?

Rust is like Cancer it will keep on spreading

This is on a euro, so I'm not keen on the DIY.

Since it's inbetween panels though and not going to be seen, is sanding alone sufficient?

Sanding could probably only make things worse.
(BODY WORK) When fixing rust spots. you sand down to bear metal and feather the surrounding paint work, of the rust. Once down to bare metal, use a rag with rust removal or thing to not have rust build up in that location again. let it dry. use putty to bring body back in to shape and sand it down smooth. remember to be wet sanding when you're near finishing the sanding so you'll get a really smooth finish. use primer filler to fill up and mini/small air bubbles that may have developed when you put the putty on. sand it down. respray over again and sand down with, like a, 1200 grit wet & dry sand paper, and use clean water while sanding. once it looks good, leave it for a couple hours to completely dry. Putty takes a while to dry, depending on how much of the catalyst you put in. get a spray can with the same colour code as the one identified on the car. spray it on, not heavily. do layers, upon layers. let it dry for a good while. might want to use a cut & polish if the colour doesn't exactly match and if your anal about it lol. clear coat it and leave to dry.
This is basically, in a nut shell.. There's a lot more to it
I can probably do a DIY on this when I get some time. :)

any part of teh car that is exposed non-treated metal is prone to rust

IE a scratch or crack or bent part etc.
Some parts will get surface rust temporarily such as brake rotors but its nothing to worry about. As for body work , clean it up and seal to avoid car cancer

holy smokes that looks way too complex for me, especially as the rust is in between panels and can hardly be seen.

Would it be a better idea to get it fixed at a panel shop (that way they can fix up the excess touch up paint as well?). How much would I be looking at?

[DC5.Raven]

you can always apply some rust converter on it man. it'll change the chemical properties of the metal and stop futher rusting. but rust converter will dry to be a matte black. so if ur not too worried the look of that then go ahead. or u cud always do that then somehow paint over it when it dries with touch up paint or something?

It is the tiniest bit of rust, but I know that from small things big things can grow.

Sounds like a pretty good idea as my car is a dark color and the trouble spot is inbetween panels. Any recomendations as to a particular brand or make of rust converter I should get? How does wd-40 match up? Will I still need to sand the area first?

no sanding needed dude. easy as. just go into local hardware shop and ask for rust converter. its a liquid and comes in like a smallish bottle (200 / 250 mls or so). instructions easy to follow. clean area with cloth then brush on and wait for dry. then if u want u can go over it with touch up paint :thumbsup:

[power_of_dreams]

Sounds good. Can anybody vouch for this technique before I go ahead?

[sid]

I've used the rust converter, good product. I say go for it as it doesn't sound like a big deal. just make sure you have a tough rag or something as at first the existing rust will start making rips as you rub against it. Unless it's like a tiny rust then you can use, literally, any material

[power_of_dreams]

The site is very small. Basically I plan on doing this...

-Removing rear bar to give me full access to the area (as it's inbetween the rear quarter and rear bar).
-Cleaning the area of any free rust and picking off any flakes that may still be around.
-Thoroughly vacuum the surface
-Rinse with water
-degrease the area (what would be good to use?)
-Masking the area with newspaper masking tape.
-Spray the area (might even spray it into a small cup or something and brush it on somehow because the area is so small).
-Wait for dry
-Claybar or use scratchx or similar to get rid of the excess touch up paint.

There are a couple of brandnames being thrown around, anybody have any recomendations?
