• If you have inserted different colored wax sticks next to each other, you may get some color blending (in which the wax from the two adjacent sticks mix when creating the car body).

• In order to create a solid one-colored car body, you must insert multiple wax sticks of the same color next to each other.

You can, but the adhesive should be applied to a clean, smooth, dry surface when the temperature is above 50°F (10°C). If the temperature is below 50°F, you can heat the surface with a hair dryer before application.

• If your car body came out only partially completed, see instructional video or try the following:
• Ensure you are inserting enough wax sticks into the machine and they are positioned next to each other in the proper alignment (point side down).  Remember, it’s normal for one of the wax sticks to protrude from the top.
• Ensure the handle is pulled all the way down in one continuous motion and the injection is completed within 2-3 seconds until you hear “Complete.”

• Ensure the mold has been thoroughly cleaned before starting your cycle.

On the underside of the launcher, each end of the rubber band should be wrapped around a peg on each side of the main launcher and then doubled up and hooked around the center tab of the moveable portion of the launcher.

Here is a picture of an assembled rubber band launcher!

• Yes, for best results, allow the wax to cool for a few minutes before opening the mold. Twist the mold slightly (as you would an ice cube tray) to break the wax free. You can also run the mold under cold water, which will help speed up the cooling process. If the car body is wet, be sure to dry it completely before applying labels. Remove car body from the mold within 10 minutes. If the body is left in the mold for any longer, the wax may begin to crack.

Simply heat up the base plate with a hair dryer to soften the adhesive. Then use dental floss to gently cut through the foam to remove the 3M Command™ strip from the surface. Stretch or peel off the remaining adhesive.

To cover existing paint or color you will need to apply multiple coats. First paint a thin, light coat and let it dry. Then repeat the process until you get the paint coverage you want.

• Excess wax on the car body can be easily trimmed by hand or with the supplied design tool.

Instructional videos include a review of box contents, items you'll need to get started and helpful tips about Hot Wheels Wall Tracks.

3M Command™ Strips can be used on painted, stained or varnished wood, glass, tile, painted cinder block, plaster, metal, and wallboard.

• The very first time you use Car Maker, you need to insert 2 wax sticks. Car Maker comes pre-loaded with 1 wax stick. The second stick you insert is not meant to fit completely inside the machine – it will protrude through the top. After you have made your very first car, only 1 additional wax stick needs to be inserted every time. Please note that ALL wax sticks must be inserted with the point side down.

Make sure the pen is fully inserted by pushing it all the way into the slot on the spray gun until you hear/feel it click. Start spraying with the nozzle adjuster pointed all the way toward the negative side (-) and, while holding the trigger down, slowly move the adjuster toward the positive side (+) until you get a nice even spray. If you’re still having issues, please refer to the troubleshooting section below.

• Once Car Maker instructs you to pull the handle, you must immediately pull it all the way down in one continuous motion until you hear “Complete.” For best results, DO NOT pump handle when pulling it down and complete the injection within 2-3 seconds. If you do not pull it all the way down to complete the injection, Car Maker will keep repeating the phrase, “Please pull down handle.”

You can combine your pens to get more color combinations. For example, you can get green by applying blue and yellow inks over each other. First apply a thin layer of one color until you get the desired coverage, then switch pens and apply an even layer of your second ink. Try making your own combinations!

• If you cannot insert or remove the mold, locate the tabs on both sides of Car Maker (underneath handle), push them up and try again.
