Looking for opinions here. What is the best combination of primer paint and coat for aluminum parts that are going to get some love taps from gravel and small rocks coming off my tires? My fenders and tongue channels are alum and I painted them myself but they took a beating on a recent trip. Is there some paint that is more flexible like plastidip? I want a glossy finish to match my diamond plate and doors but I know I’m being picky. Any help would be greatly appreciated. I’m not trying to be a pavement princess and I know some battle scars are cool but my OCD is going nuts with the dings when the rest of it looks great.
