Here is a shot of my mast at about 3 years and now at 5 years it is looking a little faded and has some places where the paint is wearing thin and a few chips from contacting things while steping(about a hundred plus times).
It was anodized and looking bad when I started.
After removing all hardware I stuffed 10 ft. fence posts in each end so I could suspended it between saw horses with out it bowing to bad.
I used a high speed air die grinder and 2 inch brown 3M sanding pad to remove any white spots and to give the paint a good hold.
I wiped it down with laqure thinner to remove any oil.
The next morning I wet down the area with the hose ( I'm working in dirt but it is an old trick to keep the dust down when ever you want a dust free paint job), one more wipe with thinner and wipe down with a tack cloth and I was ready to paint.
I use Rustolem(?) white and put it on with a foam banana roller starting at the top and working all the way around and down.
I didn't try to get paint into the track because I thought that might be a place for to much wear, just rolled lighty there painting just the top.
I waited untill the bottom was tack free and then tacked it off and put the second coat on.
Time for the job, not counting the disasembly and reasembly, four hours.
Cost for job, about $25.
It does take about a week for this paint to dry (No paint smell no matter how close you put your nose) because it is oil based.
