I don’t know anything about your truck prep prime, color, clear paints, the conditions of and application quality.
I did recently paint my old paramount I etched with vinegar and immediately primered with 2k, 1k color, and 2k clear and it’s very fine and durable. It not soft or chipping. It does take a few weeks for final cure.
I went with real car paint Lumabase in Spraymax rattle can. It’s about $40 per can filled at the local Wesco supply.
