What are the recommendations on rust treatments I treated a small section on my wheel arch about 6 months ago and the rust is showing through again. I used Loctite rust remedy and cleaned as much rust off as possible.I know cut out the area and weld but this is a very small section.

Usually for small sections that aren't rotten just lightly grind off the rust with a grinder flapper disc, treat with a good rust treatment product, then wash down with clean water, thinners and apply a good few coats of primer and finish with top coat and lacquer. Usually it will come back in time though. I do find the more coats of primer the better. I've been doing repairs on a project I have stored up and one bit I had put about 5 coats of primer on new metal, the other bit only one coat, the one coat bit was rusting after a couple of months. The other bit was fine. Mind you primer is not waterproof so get a top coat on as quick as you can if you are using car out and about.

Rust treatments are a waste of time and money, especially on panel joins like wheel arches or sills. That's because you're only 'curing' the outside, which is the last bit to show.


You do have options though. Two, but you won't like either of them:


1. Cut out ALL of the rust(most of which you can't see yet), and weld in fresh metal.
2. Ignore it until it gets really bad and scrap the car.


I have a pair of new sills for my car, which is a relatively quick and easy job. One that will probably prolong the car's life for a couple of years before the other crusty areas - like both subframe mounts - get too bad to be worth fixing. That's the butterfly moment; when the car is transformed into bean tins.

Thanks Nick That's made my day but I expected it. This small area that I treated I asked for a quote at a body shop and they quoted £ 600. More than the cars worth .I will treat it until I get feed up and then put a sticker over it.The problem is that we get so attached to these cars and don't want to let them go.

Agreed....

If you can get access to the rear of any repaired area by removing trim, it is worth the effort to use another product called Supertrol which is for internal box sections rather than exposed areas. It is superb for creeping into welded seams, and into the inside repaired uneven areas, rather than just bridging them as many wax based products do. I have used it on many occasions, and have seen it creep over a matter of weeks through a spot welded seem which was approx. 1/2" wide, and you know then that it has completely protected the 'unprotected' area between the spot welded seam which other wise would have very little, if any paint.
Now is the time you wish you had removed all the rear trim to gain access to the rear arches, and interior trim to access the inside of the sills, to do any rust prevention when the car was much much younger.....! Ask me if I have any rust on any of my Omega rear wheel arches......

That's the answer for an Omega!
