When we first got our 1972 BMW Bavaria, the paint was failing. I bought a Makita 9227C 7-Inch Hook and Loop Electronic Polisher/Sander from Amazon
I didn’t know that the paint was already dead. All the Meguiar’s compounds, glazes and waxes couldn’t save it. After hours of work, the paint would look good for a week or two.
Now, with relatively new (single stage) paint on the car, it’s a different story. After washing the car, I’ve been using Meguiar’s NXT Generation Tech Wax, Zymol Cleaner Wax or Eagle One’s NanoWax, applied by hand with a foam pad.
Then the Makita polisher, with a wool polishing bonnet or a foam pad, removes the wax easily and leaves the paint nicely polished. It doesn’t take a lot of effort and the paint shines; I’m just trying to protect it. I still dread having to wax the car, but it turns out, with the Makita polisher, it really isn’t a big effort now.
