*chickselog: 2 video's that might help, you could check how he applies it in the video and just copy it, just be sure to frequently check the paint if the correction is already done, you don't have to stick to 2 to 3 minutes per panel, it might be shorter or longer depending on the gravity of the defect you are removing and correcting.
