Alright fellas, I need to replace one panal as it buggered but once I strip all the paint off, all the small rust parts I want to treat first.
Now I saw a thred which showed a guy using something but I cant find it now.

So would some rust guru please tell me a name products that you all use? Cheers.

This process looks decent but I dont trust americans

This sort of thing might be ok for thick chassis sections but to be honest if a panel has rust the only cure is to cut the rust out and replace with new metal. Clean and paint the metal really well to prevent rust from forming again. There are plenty of examples in the rebuild sections on the forum. Good luck.

One panal I will be replacing altogether but thats as bad as it gets to be honest. My car is pretty solid and only has a few minor rust spots which I will just treat. I will take a look in rebuild section

If it's only light surface rust on a panel, I tried POR15 prep and ready, which is a liquid that actually removes the rust right back to clean metal. This only really works on light surface rust or those little rusty worm like trails you find under the paint, but I was surprised when it did actually remove the rust completely not just turn it black as so many products do. If however it's slightly pitted, then it does still work but its then best to use a small straight wire brush in a dremel and clean it as best you can first, then apply the liquid, but for more stubborn rust you need to keep it wet for ages for it to work. Another option is shot blasting, but you do need a compressor. If it's only a small area you can get a hand held gun with a rubber nozzle that recirculates the grit. In short you press the nozzle up to the rusted area squeeze the trigger for a few seconds and it blasts that small area clean. Does take a while pending rust spot size, but very controllable and you don't get grit going everywhere.

I will only be using it for very small parts of rust. Ive got a big list of things to do first but as some guys may know its all going on my 'to do list'. So im wanting to get everything ready and be organised for once. Cheers I will have a look into that POR15.

As above cutting is out is the best bet, but I found some really good stuff called FERTAN rust treatment. Its used on boats and is avalible from likes of Force 4 Chandlery. I used this to great effect on my project. You just need to ensure area is soaking wet before applying it! It changes the constituion of metal so that further rusting cannot occur. Once traeted simple wash off excess and paint.

[toms]

Agreed with the cutting out. But im literally talking about small rust parts. Rust that is just starting to show in little areas. All these ideas you keep telling me I will look into them all so cheers. It will be another month yet eacy untill I start to sand the paint off etc

[donjarr]

I hate to put a downer on things but fertan is just another rust convertor stroke encapsulator. It doesn't remove the rust just chemically alters it too temporally stop it oxidising. All it does is halt the process of oxidization. but eventually the oxidization will return, its the nature of metal. The key is to remove the rust either by cutting out, sandblasting or chemically removing it without having to paint it.


Personally for small rust like bubbles I would use a spot blaster like this (http://www.machinema...TC=RV-000512005 ) as it would allow you to remove rust bubbles with precision without damaging the surround area. However bear in mind that a lot of rust bubbles started at the back of the panel and have pushed through to the other side, so you may encounter a hole. In the good ole days we just got the lead out and leaded the panel then flatted it off, but leading is a dying art now.

So have a look at all surgestions and see what you think.

Bilthamber do deox c gel that you cover the rust in and leave an hour. It completely removes rust and doesn't just cover it up. But you obviously need to protect the bare metal immediately after.

[miniyellowmini]

I have used Jenolite in the past seemed to do a good job in removing the rust. Surface was left pitted in places where the rust was worse but minor surface rust disolved and was took back to bare metal

[minidave1991-89]

I just used good old hammerite kurust but it was only on slight surface rust patches around my windscreen until i could get it sanded for respray. Best bet as everyone else said is to cut it out and start again.

[Spitfire12]

Yep, I use Hammerite Kurust to treat small rust patches and then you could use etch primer.

[sonikk4]

I use Krust only on an area that has surface corrosion and only after i have cleaned the rust off. If the metal is pitted then its chopped out and new netal welded in. None of then stop rust permanently, they help to inhibit it but ultimately it will come back.

Most rust you find on a mini starts from behind so what you see is the tip of the iceberg so to speak.
