I bought this last November so I could apply a stain to the new fence on our property that was destroyed in a wind storm. But, the wind and rain kept us from doing so until these past two weeks. In total we have painted 620 linear feet of 6' high fence made up of drill pipe, 2x4s and 1x6" 6' tall. That's a lot of fence to be painting. We still have another 300 feet to go. Our neighbor finally decided to fix the adjoining fence so now we have more to do.This Graco Magnum made the job easy and quick compared to rolling. we put our little generator in the back of our work trailer and pulled it with the lawn tractor to the back fence. Worked beautifully. Priming was extremely easy. Painting was a delight, if it can be. Using the supplied tip of 512, it was a very nice wide pattern and covered a lot of fence. Took a bit to figure out how far back I needed to be to keep from causing runs, drips and errors. At first I was about to eclipse Pete Rose's record of runs, Hits, and errors. LOL. Then I learned that about 12"-15" works best in light winds of 5-8mph. Any higher its best to wait till there's low winds. But clean up, now that was easy. Prime it with some mineral sprits, Then with the small buck full of MS, start spraying into an empty bucket till the nozzle sprays clear. Disassemble the intake screen and wash off in the MS and blow it off. Then take the nozzle apart and clean it. With the nozzle and screen clean I just put them in the slots in the feet of the sprayer for safe keeping.So was it worth the investment? Well, ask me that question after I paint the fences again next year. Im sure Ill be smiling just as much. I won't be conning anyone to do the painting like Tom Sawyer did. But right now I'd say that this spray is worth every single penny. Painting isn't fun but it has been made 1000 times easier with this little gem.
