Doing research for my first big paint job. The base coat says a clear can be applied within 20-30 minutes. Is it okay to apply it that soon, or better to let the paint cure, sand it and then clear? I am waiting for the proper spray tips for the Concours gun for the clear anyway, but if I can get paint on now and clear it later I can still make progress, but if its better to apply clear right away, the brakes are applied for a month
