Based on how it flowed out of the gun as he was doing the spot repairs, Brian felt the paint should be reduced further before applying a full coat to the rest of the car. Though it was mixed properly, Brian told us paint often needs some fine tuning with more or less reducer, depending on conditions, and this is likely what happened during our attempt to clear the car. Brian recognized small changes in how the paint flowed out on the surface of the car and was able to adjust the mixture to get it to act the way he wanted it to. This is why painters always recommend shooting a test panel prior to actually painting the car. Get the gun and paint mixture finalized on scrap material first, and you’re not wasting time and material.
