I have not had mine overflow - YET - but if the nozzle is pushed in fully it tends to cut off. I find to push it in fully then pull out about 1" and keep a steady flow rather than full pressure it seems to work ok. Just make sure to shake off the drops at the end so it does not drip on the bodywork. Sorry - have just read that and no doubt there will be some derisory comments before long!OOH ERRRR MISSUS!!!
