Protekto-trim auto body side molding kits by Cowles or Trim-Gard are made of the finest quality materials to provide easy installation and long lasting performance.

Moldings are made with virgin PVC compounds, high quality Mylar, and 3M acrylic automotive mounting tape.

All mouldings are flexible and easy to work with.

2-inch and wider widths come with two strips of 3M peel'n'stick tape, narrower widths come with one strip.

The Mylar chrome finish is highly reflective, a perfect mirror, as seen in the pictures at left.
Molding Kits come packaged in lengths convenient for the do-it-yourself installer.

Body side moldings can be used to enhance the appearance of your car or truck as well as function as a protective barrier for those nasty parking lot mishaps.  Side trim molding for trucks, cars, vans, SUV's, RV's, etc.

Easy to install. All of our molding comes with 3M acrylic automotive foam tape attached and ready to peel and stick on. Once applied, 3M peel-and-stick pressure-sensitive self-adhesive backing not is affected by weather or road chemicals. Not available in stores, we offer our trim moldings direct to you! Why pay for expensive dealer installation?

Prevent most minor dings, paint-chips and body blemishes that can happen when someone opens their door and whacks your vehicle. Many vehicles come with decorative side moldings strategically placed at "door-ding height" to help prevent this problem. If your vehicle lacks such protection, you may want to consider installing it yourself. Installing side protective body molding is a fairly simple undertaking, provided that you take the time to apply it carefully and meticulously.

Measure: Be sure to measure the area you want to protect. Note the length of the pre-cut kits, some trucks may need two kits if you want to extend the molding to the box as well as the cab.  If you are installing moldings into slots in bumpers or body side panels, be sure to allow adequate clearance so you do not need to force the molding into place. Order enough so you have a foot or two extra to practice your cuts.

INSTALLATION:
Materials: Body Side Molding kit, Sharp Cutting tool, Rubbing alcohol, Clean white rag, Masking tape, Grease pencil (whose marks will easily rub off). A warm garage or a sunny day makes the whole job a lot easier. Do not use a heat gun, and do not heat by close proximity to a radiant heater. High heat may damage the UV protection layer over the aluminized film (Mylar).

Moldings with 3M tape are best installed at temperatures warmer than 65 degrees. Plastic moldings are more flexible, easier to manipulate and cut when warmer than 70 degrees. Smaller moldings can be easily cut with heavy sharp kitchen shears or tin snips. For larger moldings, more than 1 inch wide or 3/16 thick, a clean straight cut is somewhat more difficult. A clean sharp anvil pruner will make it easier to get a straight cut on all sizes. A carpenter's utility knife with razor blade inserts also works well, but not one with the break-off blades.

This picture shows the professional tool used by our installers to cut molding. You will note that it is very similar to a set of anvil pruners, except the blade is 3.75 inches long replaceable razor blade. An anvil pruner from a local garden store will do nearly the same job if it is sharp and clean.

Prepare the vehicle bonding surface by cleaning it thoroughly with alcohol and a clean white cotton rag. This removes wax residues so the 3M Peel-and-stick adhesive can bond to it securely. Avoid using colored cloth for this purpose, as the dyes in the fabric may leave colored residue behind.

If you do not have a ridge or line to follow on the car,
Apply a strip of masking tape to be a guide to help position the Body Side Moulding to be perfectly straight. You may want to measure up from the ground at each end to get a parallel line. Stick the masking tape at one end, and hold it a few inches away from the car while pulling tape off the roll to the other end, eyeball your line, then stick it down lightly. Step back and look to see the lines are right, change if necessary. It is easy to change the tape at this point. Once the body molding is installed and the glue sets for a few days, it does not come off!

Once the straight line of masking tape is in place to provide a guide, use pieces of masking tape to temporarily "dry-fit" the entire length of body molding in place on the vehicle.

Determine where you'll need to cut the body molding for the doors and seams for a precise and accurate installation. Use pieces of tape or a grease pencil to mark the exact locations on the molding where you'll need to make the cuts. At the door-openings, and where the molding terminates at the edge of wheel-wells, you may need to cut angles to match the vehicle lines. Allow 1/8" minimum gap for door clearance. At the hinge side of the door you may need to bevel the end of the molding so that there is enough clearance when the door is opened.

Once you've marked the locations, carefully cut the molding. The molding is made from a relatively soft plastic. Cutting isn't difficult, but it is easier when the molding is warmer than when it is colder. Always cut chrome moldings with the blade entering the chrome side, cutting down through to the tape side.

Work with one section at a time, peel about a foot of the backing from the adhesive strips and press the molding into place. Then pull on the loose end of the backing and move along the molding, pressing it into place. Do not peel so much of the backing away that thesticky glue surface can contact other dirty surfaces which could then impair its adhesion.

After it is applied to the vehicle surface, rub each section of molding firmly with a soft clean cloth to help ensure that it is seated securely. You may want to come back a few hours later, or the next day, to give it another pressure rub to ensure the best adhesion.

Open and close the doors slowly, watching to ensure that the side molding is not touched or rubbed as the door moves.

Allow the molding adhesive to set up for at least 24 hours before washing your vehicle. Maximum adhesion is reached after 3-5 days in temperatures above 70 degrees, longer if it is cooler.

Chrome Moldings are made with a reflective aluminized polyester film (Mylar) sandwiched between a UV protective coating and a vinyl backing that  attaches the film to the translucent gray base vinyl extrusion. In most cases, the Mylar film is then wrapped around the molding to the back side so the edge is protected by the 3M tape and not exposed to the elements. Care should be taken to avoid abrading the protective film, which can then allow salt and road chemicals to degrade the reflective properties of the Mylar film.

3M Automotive Attachment Tape is a .045-inch thick, medium-density white acrylic foam tape with high performance acrylic adhesives on both sides and a red release liner. 3M Automotive Attachment Tape uses automotive OEM (Original Equipment Manufacturer) approved acrylic foam core and adhesive technology. It is characterized by high peel and shear adhesion, high internal strength, high conformability and excellent plasticizer resistance. Typical applications would include body side moldings, rocker panel trim, claddings, bumper trim and other automotive trim components. Because it requires no drilling into automotive painted surfaces, 3M Automotive Attachment Tape eliminates the concern for rust development associated with the use of mechanical fasteners. The unique stress relaxation properties of the tape's foam core allow it to expand and contract with temperature changes. Stress forces of an application are dissipated throughout the foam core, providing excellent long-term performance. The viscoelastic properties incorporated into these tapes allow it to conform to surface irregularities and gaps, providing a better fit by compensating for some part-to-vehicle mismatch. The use of 3M acrylic foam tapes eliminates the unsightly appearance of bolt, screw or rivet heads associated with mechanical fasteners. Surfaces remain clean and smooth, contributing to styling and aerodynamic design. The use of acrylic foam tape can eliminate steps in the installation process, often requiring fewer parts and less labor time.
