EvanQ,
Reducing the base cote will only make the color less opaque. Be careful reducing the clearcote as much as is indicated above. Remember when using PPG the clear is mixed 1:1 with the activator first. Then you can safely "Reduce" that mixture up to 20%. If you want to experiment with a greater reduction do so on a test piece please. Reducing will make the Clear thinner and it will sag easier, and might even get brittle-----
