When applying a top coat to a bike frame, is it more effective to use a single, thick layer or multiple thin layers, allowing each to fully cure before adding the next? Conventional wisdom suggests that a single, thick layer provides a more uniform finish, but Ive heard arguments that multiple thin layers can reduce the risk of drips and runs, while also promoting a stronger bond between the top coat and the underlying paint. However, doesnt this approach also increase the risk of dust and debris accumulation between layers, potentially compromising the finish? Are there any specific products or techniques that can mitigate these risks and ensure a flawless, high-gloss finish?
