i think the early webers had that indent. as to the wheels i always take them off and get the junk off with cleaners and then finish them off with the 0000 steel wool. i kinda get anal about it. i even clean up, finish and almost polish up the ash catcher. i always treat the raw aluminum with a very light treatment of pam. seems to be holding up so far. i treated one of my kettle legs with a high temp clear paint. i'll see how that comes out as time goes by.
