How To Prep A Car For Paint. Spray two to three coats of high-build primer over the entire vehicle after you are satisfied with your sanding scuffing or removal of paint. Wait 15 to 30 minutes for the product to dry then add a second layer.
Its all in the preparation. The water acts as a lubricant and vehicle to remove the paint dust that would normally just clog up the sandpaper and get in the way. If youre only touching up a small patch use a sanding block but if youre painting the whole car youll want to use an electric sander.
The vehicle should be degreased one last time before painting begins.
To prepare your car for paint youll need to sand away the old finish and add a few coats of primer. When paint-rolling there is no need for a mouth cap. Wait for the second layer to dry all the way before you start painting your car. Apply minimum three maximum of three coats of paint to your car.
