How to Repair Motorcycle Fairings with PlastiFix

VideoClick here to see the video of this motorcycle fairings repair

Step 1

Motorcycle fairings are often discarded because of small cracks in the motorbike fairing. Replacement fairings may not be available or they may be too expensive. We will recreate the missing piece on this side so that it matches the piece on the opposite side.

Clean the damaged area. Some contaminants, like tar or grease or sticker adhesive, will not come off with soap and water. Super Clean Plastic Cleaner is a mild solvent based cleaner that will remove these contaminants without attacking the plastic. Use a clean cloth or paper towel and wipe in one direction to avoid recontaminating the surface.

Step 2

Use a rotary tool with a teardrop shaped cutting bit to remove the paint where the PlplastiFix will be applied. Grind away some of the plastic so that after the PlastiFix is applied, the surface will be flush with the surrounding plastic.

Step 3

Apply aluminum body tape to the backside and use a body spreader to get a good seal of the tape to the plastic fairing.

Step 4

Use a body spreader to help put a small bend on the edge of the tape. This will help keep the PlastiFix contained.

Step 5

Sprinkle a layer of the PlastiFix powder onto the tape and the repair area. It may help to get the piece as horizontal as possible to keep the powder from running off of the area. Once the powder is applied, squeeze the PlastiFix liquid applicator bottle and apply liquid on top of the powder until the powder is saturated.

Continue layering the powder and liquid until the desired thickness is achieved.

Allow plastifix to cure fully before removing the tape.

Step 6

On the backside, we added additional strength to the repair with fiberglass tape. Cut a piece of fiberglass drywall tape that will fit the repair area and press the tape into place.

Just as was done on the opposite side, layer the powder and liquid until the desired thickness is achieved. Allow PlastiFix to cure fully.

Step 7

The plastifix will be rough and will need to be shaped and contoured. A pencil and ruler will assist with grinding to the proper shape.

Tape a piece of paper to the undamaged piece and use a pencil or a crayon to get a rubbing of the shape.

Step 10

Cut the shape out of the paper and flip the paper over. This is the contour that we need to transfer to the damaged part.
