These did a good job, but there was lots of overspray, admittedly it was first time using the sprayer as well (Graco Magnum X5). I decided to try these new tips, 'True Airless', after reading about them on Graco's web site. After painting a 12 foot section of fence I can definitely say there was much less overspray. I also used a 415 'True Airless' tip to do a brick foundation, on a house built in the 1920's, which also turned out great. Overall, I will only use 'True Airless' tips whenever possible.
