If this lip is painted or installed on vehicle!!!
Please test fit the part to your vehicle prior to paint or install. This lip is made out of
polyurethane (PU) material to be bend-friendly. If the part is out of shape, it will return to its
original shape after heat up + cool down in one of the following ways:
Heating Preparation:
1. In the summer if it’s hot out there with 86°F (30°C) or higher just use the sun unattended
for 30 minutes to 1 hour. Remember to put the lip back into its lip bag while heating.
2. Use heat gun (hair dryer) if available. You may bend the part to the ideal shape while
heating it up with your heat gun. Typically holding the heat gun 1 foot away when
heating up a particular spot for 2 to 3 minutes (hair dryer may take a bit longer) of heat
up time.
3. Once the part got softens, you may bend it back to shape, and quickly cool it down with a
fan after.

manufacturing, it is necessary to carefully prepare and utilize paint products that are flexible or
can be used with flex agent additives. (Consult with an Automotive Paint Supplier for their
recommendations on specific brands and products).

flexible Urethane parts.
6. After primer has dried, wet sand using 400-500 grit wet or dry sand paper.
