how to remove rust from mustang 67???

[richardgenox]

Should i sandblast or use wire brush?
any tips of getting rust off quicker ?
im trying to get rid of the rust and wiring is taking quite a bit, and cant manage to get in places that are to small for the wire brush

Big area or small area? Surface rust or cleaning up the area around a rust hole to weld to? If you're doing the entire car media blasting is an option.

big and small areas, surface rust and i was thinking about buying a portable sand blaster but not sure on which ones are good

It really depends on where the is. Having been in the auto paint & body business a while back, I can tell you one thing for sure. Unless you get rid of ALL of it, it will come back. It's not if, but when. Rust on the surface needs to be sanded or ground away completely to bare metal, any necessary smoothing body work done, then etch primed & painted.

If you're seeing blisters coming from under the paint, unless there is a break in the paint surface where moisture is getting through, it's rusting from the back side. From my experience, (I live in the rust belt, by the way) you're seeing the first sign of rust through which means it's the deepest point of a much larger rusted area that you can't often see. If so, you can try grinding back and filling or welding in a patch, but from my experience, it's like an iceberg. You see the tip, but most of it's hidden.
Panel replacement comes next if the previous steps aren't enough.

You mentioned that you can't get into places, so if you can't sand/grind it all away, or if all the area can't be accessed, coating or saturating tight areas with a rust converter can help especially if you can't afford or don't wish to go nuts with body work. The products I've used are Ospho & Plasti-coat Rust Converter. both leave a primable surface. I've used POR-15 paint on the underside rusted areas with success. On small parts that can be removed, I'd recommend electrolytic rust removal (google it if you're not familiar) then re-painting.

im wiring the rust away and then using por-15 after, but im just wondering if theres a faster way to get rid of the rust

Por-15 won't get rid of it. It will (based on what they say & if it's the product I used...they may have others)) seal it off. I think that if it's in hard to or impossible to get at places, I'd use a rust converter product & then seal it off with a paint product. In tight places, like down between stuff where parts may rub/vibrate together under use, I like the idea of a chemical conversion of the process. Also, the rust converters are lighter in viscosity & might flow better into tight places than paint, although you could probably thin that a bit too.
