Buy a Sticker

There are a number of mail-order companies that make custom auto stickers, but so far I've only found one that meets all of my criteria:

• Maximum custom size of at least 40 inches long by 4 inches high
• Accepts custom graphics (not just text) via uploaded art file (not constrained to fixed format).
• Waterproof
• Easily and safely removable (and option for reusable)
• Paint-safe
• Professionally made
• No minimum order - you can order just one sticker.
• Inexpensive ($11 @ qty 1)
• Business highly rated on Google and Facebook

The company is called Sticker Factory. Here's a link to the relevant page on their website: https://wantstickers.com/print/custom-shape-auto-body-decals/.

*** I haven't evaluated this product or researched beyond material available on their website yet. (So far, I've just been printing my own banners as described on the "Do It Yourself" page). If you try this or another company out, please send an email to me at jim@bumperbanner.net to share your experience with me.
