You might be thinking to yourself "big deal!" Well...
Yes, something like this probably exists commercially. And it's probably over-priced.
Yes, the G.R.L., Barry McGee, and Citizens Against Ugly Street Spam have made similar tools.
Yes, it's not challenging to make and hardly requires instrcutions.
Yes, it doesn't take a genius to think of this and you probably would have come up with it yourself.
BUT, if this is what you need, it's an awesome tool that you can make for at most $6.
Also, at $6 it can get lost or become disposable in a pinch.
Once you know this tool exists and how to use it, hopefully you will be compelled to make one to paint over hard to reach advertising and beautify your neighborhood like someone I might have heard about maybe did one time. It's quick, easy, and fun.
Step 1: Get your materials
1. A wood broom/paint stick. Or any stick you can drill into. The one I found was about 5 feet long and $3.99. Perfect for what I needed it for.
2. Foam brushes. Found in the paint section. I hear foam brushes are good if one was to often walk around painting out advertising and couldn't always clean their brush. Each one costs around $.75 and I try to use them a few times. Get the ones with wood handles, not plastic.
3. 2 screws
4. A small can of black house paint.
1. Duct tape. This can help support the brush and keep it from moving. Especially if you shear the head of the screw because you didn't pre-drill.
2. a drill bit to pre-drill your holes. I didn't have one handy, so I drove the screw straight in, cracked the handle, and sheared the head of the screw. Not ideal, but it is called the "Quick and Dirty Low-Tech Ad Buffer" isn't it?
