A popular myth is that you can simply wipe a car down with lacquer thinner then spray paint on it.

How to prep a rusty car for paint. As we have already established, there must be nothing between the new layer of paint, and the surface of the car. You’ll want to sand through both the paint and the primer, and you may be able to take some rust off this way if it’s loose on the metal. Move the tip of the media blaster back and forth over the engine.

If you’re dealing with a lightly rusted surface, you may just need to give it a quick scrub with a brush. Scrub partially rusted metal areas with a wire brush to remove flakes and powdery surface rust, then prime. The automotive version of this product will act as a sealant (or rust encapsulator) and should be applied before painting or bedlining the floorboard.

Before moving on to paint, check the primer instructions. If you are preparing just one panel or do not have interior rust then it is possible to grind the surface with a flap disk or grinding disk that is between 30 and 60 grit to remove most of the rust. Creating simulated rust on your hot rod is not a complicated process.

However, badly rusted metal areas need more prep work and possibly a special primer. For instance, paint within an hour of priming, or after 24 hours drying time. It's the same as the etch and prep, or whatever it is por15 uses.

It has to be clean, very clean. Scrape off light, loose rust with a wire brush. Good prep makes the car paint job last a long time, and bad prep ruins good paint jobs.

Wait for it to dry (air helps), and paint. Use the blaster over as much of the engine as possible. If you don't neutralize/remove the rust, it'll pop out again in a year.

Another way to use it is as a wash, brush it on the already degreased metal till the rust is gone and rinse off. Wipe the car down again with solvent and a clean rag, careful not to use too much, or it can wipe off the primer. A summary of the layers to this point is:

Rub down until you reach sound paint all round, but not beyond. On sheet metal you can rub with a dampened rag to remove rust, wipe dry, and paint in 15 minutes. Especially something as dangerous as rust.

2) you paint the primer before it's totally done reacting and you get bubbling and reactions that result in the paint not laying down right. At that point as you see in our photo you will have remaining pitting. You don't need to get down to bare, shiny metal—just clean off the flakes and powdery surface rust that prevent paint from adhering.

Wipe away dust with a clean cloth. It is mostly a matter of layering different colors of paint to create the final look. Start with a wire brush (photo 1).

The phosphoric neutralizes the rust. A paint scraper or metal putty. If your car has a patch of rust resting somewhere on the surface, it will spread and damage the paint entirely.

1) you don't sand of all the paint and there's rust underneath the paint that the primer doesn't get to that then continues to grow. Start low and work your way up. Write brush then scrub it down with phosphoric acid, found at most hardware stores, let it sit for a few hours then rinse it well, then paint it.

In addition to correcting surface imperfections resulting from the rust, paint creates a surface barrier that halts the oxidation process, barring additional rust from forming. To prevent bubbling, flaking and pitting over time, you should take particular care in. This will basically help to protect rust from spreading by providing a watertight barrier.

Here are some tips for how to prep a car for paint, as well as some mistakes to avoid. As most cars have iron or steel in their frames, the most convincing rust effect is simulated iron oxide, which uses a number of colors in the red/orange/brown. The soda media will blast away loose paint and rust from the engine block, exposing the metal underneath.
