Step 1
Decide on a design for your propane tank. You can paint a propane tank, but by law it is required to be painted a reflective color. Talk to your propane provider before you paint it and they can help you decide if a color is appropriate. Light colors, such as whites, yellows and tans are considered reflective. This requirement is in place to keep the propane tank from getting too hot, since dark colors absorb heat.
Step 2
Non-permanent decorations are best, especially if you are renting the tank. Decorate for holidays by using wire or magnets to hold the decorations on the tank. A Christmas wreath attached to the end or garland-looped around the tank and held up with magnetic hooks can make it look festive.You can also use magnetic hooks to hold bunting for the Fourth of July, metal flower cutouts for spring and summer, and metal-leaf cutouts for fall.
Step 3
If you want to decorate the propane tank permanently and you get the OK from the propane company, you can use your imagination to come up with a unique design for the tank. Some options include: painting a smiley face on the end, decorating the whole thing with green stripes to mimic a watermelon, or painting it pink and adding a pig's face and tail.
