It's very important to use it as much as possible as it helps stop the sheet metal from ' drumming ' , this is what telegraphs most of the noise road , engine , tires etc. into the passenger compartment .

However , when using it inside the doors , behind the seat and so on , it's also very important to stop it 1" minimum below the lower edge of each panel , this allows the normal amount of water precipitate to not get rapped and cause rust .

Similarly when you're doing the inside of the roof , stop before you reach the edge pinchwelds .

Be sure to take some time and thoroughly clean out the rain holes in the bottoms of the doors etc. ., not just of leaves but also the 40 years accumulation of dust / mud , insects etc. as all these collect and hold moisture .
