same like me. I'm using diff brand as well which is better at the nozzle. The blady wd-40 nozzle is useless as the small blue thingy that you use to attach a small pipe always bust out. So now I switch to SELLEY'S RP-7.
The new packing I still saw the little blue thing in there. So, don't want to risk trying that again. Because one it drop out, the whole can is as good as nothing already.
On last Saturday I went to a carwash and didnt shut the door properly and i found out that my carpet is all wet, and worst the carpet padding(sound proofing) is all wet!:rolleyes...
