I've been using swirl x with a da polisher to remove most of my swirls but there are some areas that have some deeper scratches where it looks like I need to go for a more of an abrasive compound. I would like to try Ultimate compound for those areas but do I need to follow up that with swirl x since I'm not sure if UC leaves swirls or halos after use? This is a classic car so I want to becareful on not going to aggressive. I be already try using a more aggressive pad LC orange on the areas with swirls x but still not getting it out. Any advise
