All cars used to be brushed. And once its wet sanded, it will look nice.

 

Yeah but you didn't use primer...

 

The rust spots were brought to bare metal and primed. And the chips and scratches smoothed out. Primer would only be needed there, because otherwise everything is smooth and even.

 

I painted my 51 ****** wagon with a roller and some spray Rustoleum and it lasted at least 5 years... and they areas that started looking a bit rough after five years i just sanded them a bit and touched them up.... it looked great... probably better than it did from the factory, the only issue i had was i painted the door panels white after i painted the base forrest green and it took a lot of coats to stop the green from bleeding through....
