    Hi Guys,

    I have been reading some of the old threads regarding sanding down rust and protecting the mental as much as possible on cars.

    My car has some very small service rust spots and stone chips from the roads, all down on the sill areas really and some slight early signs of rust on the wing arch by the wheel on the very edge of the mental.

    I want to tackle this before it gets any worse... i have listed below what i plan to do from reading threads on here can anyone tell me if sounds right.

    1. Am going to sand down the rusty spots and stone chips with a little sand paper, apply some bilthamper gel to make sure all the rust is off the spots and will help with any hard to get to areas with paper.

    2. Clean the bare mental (degrease) apply some epoxy 2k primer looking at the Lelchler one everyone mentions on here as it will be brushed on or dapped on lower parts of the car so wont be noticeable as such if its not smooth service once dried.

    3. finally paint or touch up the stone chips with original car colour probably use a 2k direct gloss as its a white car.

    I understand it will be expensive just for very small amounts of rust/chips but i will use it on some areas under the car also once the weather is a little warmer.

    Thanks
    Matt

    Autocorrect hates you. :laughing:

    What car?

    On the sills and wing are you absolutely positive that it's on the outside and not coming from the inside?

    Sorry for any bad spelling.

    Yes it is on the outside side it's only stone chips from the road. Some parts are where paints flaked off a bit. On the wing it's only very very slight just don't want it going any worse.

    If it's only stone chips you are maybe giving yourself more bother than you need.

    Can you scrape the worst of it with a screwdriver or chisel then clean it with a wire brush in a drill, or better still a dremel type tool and then just go through the steps that you propose.
    There isn't much point in sanding out side the damaged area and it will look better if you keep the repairs as small as necessary.
    If the rust comes through again (after a couple of years) it's simple to repair again.

    My method for this type of repair is to clean it, spot blast to clean metal with a handheld spot blasters and then straight on with the primer then topcoat with a touch up brush, allowing time for it to dry between coats.

    Have used numerous formulations of “Rust removers” (usually based on Phosphoric acid) over the years & without exception all have proved absolutely useless. I agree with Dcal the only way to guarantee rust removal is by abrasive blasting.

    Well that's really what i thought of doing, its only some parts of the rust is only very light could probably scrape some off with my finger nail. As they are stone chips was looking at using a sandpaper type pen to get the rust off without damaging surrounding good paint. I just thought using some of the Bilt Hamper gel would help get it off without damaging good paint.

    Then like you re do it when it comes back in a year or two.

    Yeahi hear what your saying with blasting but its something that i probably can't do or dont have the funds to have that done at the moment. the Rust really is very very slight. I just want to tackle it while its little and slow it down as best i can really. There just mainly tiny stone chips that have gone rusty.

    The BH deox gel is very good. Remove any loose flakes and cover the gel with cling film so it doesn't dry out. It might take a few goes but it will even get into pitted rust and dissolve it.
