Noooooo not a needle scaler!! Lol. I couldn’t stand using thoseThanks guys looks like I’m best off with some good old hard work. Wire wheels and a needle skaler. I also have an industrial pressure washer to help remove the surface rust. then either POR-15 or something similar.
Cup brushes on an angle grinder will be perfect for what you want to do. Especially if you’re not pulling the cab or drivetrain. And if you want to save some money, check out dominion sure seal “Dom16”. Pretty much the same thing as por15 for half the price, and way less steps too it.
