Rustproofing, how to do it properly?

toastedpickles

Hi guys, long story short, I'm picking up a "modern classic" ,well what i would consider one anyways, on saturday, and want to get stuck into it straight away, first to be done is rust proofing it, and removal of whatever surface rust is on there, i've checked it over and it seems fairly solid bar one or two patches of surface rust on the doors and bonnet

My intentions are to strip the car as best i can, I don't have many tools or a garage so I want to get it done during the good weather, rust proof it with waxoyl, kurust or hammerite, and re assemble, would this be right?

So can someone here, give me a guide as such to how to go about doing this properly, or point me towards a file/video, or anything on the topic

Thank ya!

Maybe a hint of what make and model would be a help. Personally I think some people go overboard, when a simple bit of retardation of rust might suffice, keeping the car indoors is the best rustproofing ever, in Ireland anyway.

Grind the visible rust off with a wire brush then paint a rust remover (phosphoric acid) into the bare metal and let it dry into, make sure its well dry, then paint a zinc primer onto that and go from there with your paint.

Hi,

It's a job I have to tackle on my own C900 too. There are a good few threads over on uksaabs detailing areas that would need particular attention on 900's...drive shaft tunnel, inner wings, battery tray, door bottoms.....

Bilt hamber products, Por 15, Fertan and Rust Bullet are all worth looking at.
I brought mine back to bare metal and repainted with rust bullet.

Thanks for that, I've started getting stuck into it, there's a bit more rust than I expected, so I'm thinking maybe sandblasting or something at this stage, but that would be a bit pricey, so i might strip the car down and go to town on it

I've started rustproofing my 78 bmw but after wire-brushing and sanding the rust off I applied that red oxide stuff as a primer. Would this be ok as a base to paint over or am i just wasting my time?
Was also thinking of waxoyling the hard to reach inner panels / frames etc.

Just FYI but I would use Dinotrol instead of Waxoyl, its a superior product and available from CleanCar.ie, I have no affiliation with either company or product. You can also get manuals from Dinotrol about where to apply and what product to use.

The first thing I would do is strip undergaurds, wheel arch covers etc. and git it a really thorough clean, get all the mud/muck and other crap off it. Let it dry for a few days, treat the rust as the guys say above and then go through each part, panel by panel. Take your time so you'll never have to do it again. Warming the Dinotrol prior to application makes it far easier.

Yeah had heard of Dinotrol and will look up that website thanks.
Guess there's no quick fix just have to be patient and do it once.

Thanks for the tip, I've checked the arches and they seem ok, the worst of it seems to be the doors and the engine bay, so the first thing im gearing up towards is getting the engine out and taking care of that area, then work my way back through to the boot
