bob, good day!
since you ordered a seal kit, well, looks like you'll be sealing those seams soon, walah, leaks gone! cool! i'm with Tim K, usage sealed my WSM's very tight! catch is, the more you use it the more cleaning there will be for the adhesive... along with Tim, i also agree with Andrew, some easy hand bending of the factory door will help there as well. it is funny that weber put the metal rolling edges as they did, yet they are reversed which allows rain, over night dew and melting snow into the base and that the door was not constructed of a stiffer aluminum or the same gauge metal as the unit... as they say, oh well! good luck, you got it covered Sir.
