First time restoring car, having problems figuring out how to remove some rust. I stripped the paint down on the hood and sanded it but still getting small rust specks.
Thx in advance.

Keep sanding, get it to clean shiney metal, If holes develop you'll hafta cut it out and weld in new metal.....
Welcome to my world, been sanding, welding, cutting out & replaceing for months now.....ARGHHHHHH
Pits in metal can be removed with Ospho. It's sold at NAPA.

Rusty steel can be converted with acid type treatment like ospho, or phosphoric or even diluted muriatic, also there are metal etching epoxys that work great. as long as its solid u dont have tto cut it out. hope this helps.
You can build yourself an electrolysis tank to de-rust your parts,,anysize,,,,easy proccess. Here's a link to show you how good this method is.

We do have a in ground pool and the kids hardly use it anymore:eek: I can see the hole car going in as I type!:eek: :whacked: :LOL:
I can see a lot of guy's sleeping on the couch for doing that,,,thats ok though,,,just park the couch near the pool.
ok....first thing clean the metal good then use metal prep,(sold at your local auto paint shop) then use an apoxe primer.
Don't laugh too hard. One of those plastic wading pools works quite well for doors, fenders etc.

Just scrub the surface with a scotchbrite and some metal prep. When the specks turn black, they are no longer "rust". They are now iron phosphate, and can be primered 30 minutes later.
Ospho works great to convert rust but beware. It does some tricks that depending on what you are doing with the rusted part, you may not appreciate. It leaves a white powdery residue that is hard to get rid of despite directions on the container that say "Just wipe it off." Any ideas out there?Quote:

Ospho has one other quality that isn't talked about much. If you use it for spot rust and get it on adjacent paint, it can lift the good paint. I used it on a John Deere tractor, on recommendation from my friendly Ace Hardware man. He said to paint it on everything and it would kill the rust and etch the old paint making the new paint stick better. Sounded good, so I followed his advice. The next day, the paint looked like it had been coated with stripper. Between the white powder, and the wrinkled paint, the job ended up a mess that required sandblasting and a complete paintjob from scratch. Mad at myself for not trying it on a test surface first. Ospho is good for treating rust. Just dont get it on good paint. :CRY: MetalPrep converts the rust and doesn't leave a residue;) One other point. You won't get help from the makers of Ospho, SKYBRYTE Inc. You can't find them on the net.
A suggestion on metal prep:
Many products require a water rinse after application. These are a little harder to get the residue off.
I use an R&M product that containes alcohol, and does not require rinsing. ( 801 Metal Prep). Just wipe it off while it's still wet. If it has dried, rewet it and wipe it off. It will leave very little behind. I always follow with a wax and grease remover, though it might not be necessary. I was told this neutralizes the acid.
