I painted the entire inside and out of a 1989 Jeep Wrangler with this metallic Gunmetal raptor liner… It was simple! I would highly recommend this product… Just make sure you prep everything properly. Once that is done, it’s very simple to mix and spray the custom color raptor liner! The bottle literally screws onto the gun can you point and spray. Clean up was a breeze, too! Just get a big jug of acetone and dip the spraygun into the acetone to spray it out and wipe it down. It took less than five minutes to clean everything up.
