Picture of Removable, Custom bumper stickers
Sometimes you want to to able to have a removable bumper sticker - for instance, you lease your car and want to remove all the "My Child Was Citizen Of The Month at Einstein Elementary" badges before you turn in your car.  Or perhaps your political leanings change over time, or you are embarrassed to display a losing candidate's sticker after the election. 

Most bumper stickers have notoriously agressive adhesives on them, and can damage your paint when you finally decide to remove them.  This Instructable will teach two skills - the first is a simple way to create a removable sticker from an existing sticker, and the second is how to create a custom bumper sticker. 

This presupposes that your vehicle has some steel on a panel that you want to display the sticker upon. If you drive a Corvette, this won't work.  It also will not work on the actual bumpers of cars made in the last decade or so, as nearly all of them have plastic bumper covers. Most modern cars' trunks or tailgates are still steel, so this should work somewhere on your car or truck.

Materials needed:

- flexible magnetic material
- bumper sticker
- windex or other glass cleaner
- squeegee
- paper towels
- straight edge
- razor blade or exacto knife

Step 1: Get magnetic material

The first step is to acquire the flexible magnetic material.  I got mine at TAP plastics, which is a west-coast plastics supplier. It is sold by-the-foot, and comes on a roll that is 24" wide.  This is the key ingredient to this instructable, so google "flexible magnetic sheet" if the is no place like TAP in your neighborhood.

One foot of this material is enough to make a several stickers.

I use "magnetic vent covers" sold at Lowes, look in the aisle with the air filters and air vents.

Why do you have to wet the magnet? the bumper sticker has an adhesive backing.

Wetting the magnetic material with glass cleaner accomplished two things: It gives you a moment or two to reposition the sticker and also allows you to easily squeegee out the bubbles. If you put the sticker down "dry", ya gotta do it right the first time - a skill I have yet to master :-)

I did this awhile back and both of the ones I made were stolen within a day. Must have been too political.
Places that make signs for businesses usually have the flex magnet material. Sometimes they sell their non-white material at a discount.
