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.
sorry..:) really wanna know coz as we read this forum everyday.. everyone is selling good product a few knows how to installed and tuned it. So my question is..
