I want to remove a small rust spot in my car.

I guess I could wire wheel brush it.
I could use white vinegar and then baking soda? (Does this work?)

I have a 6 gallon air compressor and it's a small rust spot.
I thought it might be a chance to look into an entry level blaster?
But, I am afraid of lots of residue that will he hard to clean up.

Can you guys give me some ideas?
Sand, bead, soda? Please school me on the basics.

I saw on old thread mention this Speed Blaster. Is that a good choice?

Trunk and engine bay.
It's a closed space, so is sand blasting residue a problem?

I am new to using tools, so I'm sorry for the stupid questions.
I am trying to learn as best I can.

Go to amazon and type in (SPOT BLASTER) it will show you a self contained unit for around $48.00 bucks. I have the speed blaster and the spot blaster. For your application no mess use that to slow down the rust. Figure out where it started and treat that too.

those small self contained sand blasters always seemed like they would have a lot of issues with being gravity fed and lending themselves to being in awkward positions, ( engine compartments?) and as Jobo stated, they need enough air supply to work efficiently, which it doesn't sound like you have. if its just a few small spots, maybe just a small straight or 90* die grinder with a small wire wheel bit or roloc pad. plus then you have a die grinder which is useful in a lot of other places rather than a somewhat specialized niche like a small sand blaster.

My spot blaster works well with the small garage compressor that I have. Which happens to be a craftsman oil less that puts out the same as the OP compressor. Granted if you have 60 spots you wanna do the Comp is gonna have to catch up but for just a few spots should work.

Sandblasting usually results in finding sand in the area you worked even years down the road. It gets into everything and if there is any oil or grease on any surface the sand will stick like glue. If it gets into any wear part it will destroy it.

The best way to use a SB with any medium is to remove or isolate the part. You can meticulously mask off your area to control the bounce and distribution of the sand or other medium. Take any sandblaster outside and clean something for just a few seconds and then look around and see how far you will find sand.

That having been said, it is an excellent method for removing all the rust kernels from the pitted metal. If the surface is anything but bright silver, you didn't get it all. Some rust appears as black. And, if you think you know where all the rust is, there is usually many more times than you figured once you start in. For instance, the back side of any affected area.

Rust is a plague. Those in the biz call it the "Tin Worm."
