#7 is a glaze which doesnt have any swirl removing capabilities. It should leave a deep wet look to your paint. For Meguiars swirl removal products I love using #83 DACP if the spiderwebbing is pad and then follow that up with #80 Speed glaze. You can follow that with #7. You can apply #7 with a finishing pad on your pc at a lower speed. You shoudl be able to find #83,#80, and #7 locally. IF auto stores and body shops dont have it they shoudl be able to order it for you. Remember to clay your vehicle prior to performing any of these steps. On top of #7 you can go with a pure carnauba like #26 or #16 if you can find it. You may also try NXT but I think you would want to skip the #7 becuase I dont think they would bond properlly.
