Default Changing color of frame

I bought a restored 1 1/2T chassis ,complete except for the engine.
The color is silver gray and I want to paint it black.
It appears that the metal was blasted as the pitting is not too deep and very clean.
I tried rubbing a remote area of the paint with laquer thinner,brake fluid and carb cleaner.
It was untouched.
Any suggestions how to overcoat this paint ???

Sounds like your frame may have been powder coated by the resistance you are finding trying to remove the finish. If you determine this, I have scuffed the surface with a DA with 120 grit and repainted it with enamel which held up very well.

To clarify: all chassis and running gear parts have been painted individually,
before assembly.

Just paint it as Krylon32 recommends if you wan't it a different color. You nor the factory needs or did paint things separately.

Use a high quality etching primer and then then paint it.
Call Eastwood and see what they sell.

Primer is usually for use on bare metal. If the base paint is in good condition I clean and scuff only before top coat. the less build the more solid the job.

Could the coating be Imron? I heard that stuff is really hard.

Or could be PoR 15, maybe KBS Rust Seal. I have used the Rust Seal on sandblasted transmission parts. Once cured, it is hard. Sand paper just scuffs it enough for their top coat.

Or...re-sandblast the frame; no need to remove the coating that's on there, but sandblasting will provide a good 'tooth' for your desired paint system to adhere to.

Here is an approach. First determine what you would like to pain it with. Take a small part off the chassis and scuff it with sandpaper and paint it. If it looks ok and appears to have stuck you should be ok. I have doubts about a truck frame that big being powder coated but I could be wrong.

That is a sound idea.
