While the engine was getting prepped for paint, I realized that the only areas that haven't been cleaned up on this charger were the outsides of the front inner fenders and the bottom side of the front fenders. I got my needle scaler out and hit these areas to remove the undercoating. If you haven't used a needle scaler yet, you should try it. Just be sure to wear ear/eye protection and a mask. I made a short 3 min video on youtube to show how well a needle scaler does. I've used the torch/scraper before but never will again.
