Bryan,
Absolutely. The wind speed effects the quality of the line and increases the likelihood of over-spray. This is especially true in low pressure conventional airspray machines. Airless machines are less effected due to the high pressure and velocity of the paint.
On a boarder line day I would suggest on an airless machine going with a larger fan tip and placing it closer to the pavement. This will reduce the opportunity for the wind to disrupt the spray pattern. But when in doubt, wait it out! You certainly don’t want a nasty looking job but more importantly you don’t want to be paying to have multiple cars detailed due to overspray.
Last note that DAF Scale which provides a guideline for sealing and striping does take into account wind speed.
Thanks,
Greg
