This is my first time painting my car's plastic bumper and of course I made a mistake. I forgot to put on a layer of primer before the base coat. Now the base coat is already on, should I sand it off and start over or bite the bullet and continue with mid coat and clear coat?
Before applying the base coat, I sanded the entire bumper with 400 grit wet sandpaper. 60% of the area are down to bare plastic.
If I continue without the primer, how long will it last before peeling again?
