Repair cracked and broken motorcycle fairing with PlastiFix


Motorcycle plastics are often discarded because
of small cracks in the fairing. This demonstration shows how to use PlastiFix
to repair a crack in a motorcycle fairing. Align the crack. You may need to hold the alignment in place
with aluminum tape. On this crack, though, tape is not necessary. Some contaminants like tar, grease, and sticker
residue will not come off with soap and water. Super Clean is a mild solvent based cleaner
that will remove these contaminants. Use a clean cloth or paper towel and wipe
in one direction to avoid re-contaminating the surface. Use a rotary tool with a teardrop shaped cutting bit and grind about halfway through the
plastic along the crack line. Be sure to round off any sharp edges. Use a DA sander with 180 grit sandpaper to
remove the paint surrounding the damage and to radius into the damage. The technique to apply PlastiFix is shown
here in slow motion. Squeeze two or three drops of liquid into
the powder, then use the tip of the needle to stab
the ball of liquid and powder. The hole of the needle is on the side of the
needle, not at the tip. When you transfer the ball of liquid and powder
to the crack, give the bottle another squeeze. The liquid will run down the side of the
needle and wash off the ball. Continue using this method until the crack
is filled with PlastiFix. Allow PlastiFix to cure fully before working
on the opposite side. Use a rotary tool with a teardrop shaped cutting
bit and grind away about halfway through the plastic along the crack line. Be sure to round off any sharp edges. Just as you did on the opposite side, fill the v-groove with PlastiFix and allow PlastiFix to cure fully. Use a rotary tool with a teardrop shaped cutting
bit and remove any excess PlastiFix until the level of the PlastiFix is slightly below
the level of the surrounding plastic. Mix and apply epoxy filler to the repair area. Allow the filler to cure fully before sanding. Sand the filler to the correct contour and
finish sanding with 320 grit sandpaper. Sand any area where primer will be applied
with 320 grit sandpaper. Tight spots may need to be sanded by hand. Apply a high build flexible primer surfacer
and allow time for it to dry. With 320 grit sandpaper, sand the primer until the entire part has a smooth finish that is ready for a topcoat. Apply the topcoat according to the paint
manufacturer’s recommendation. Here, we are applying a base coat clear coat. Here’s how the crack looked before and after
it was repaired with PlastiFix from Polyvance.

  1. Leaving aside the whole issue of how bloody stupid plastic fairings on streetbikes are…just makes your life more complicated and expensive, for zero benefit below 100MPH…

  2. Can I ask what gauge needle you used in the video and where you got it from, not seen one with a side release like that before!

  3. how flexible is the repair in comparison to the rest of the panel. pretty easy to make something look like its repaired but how easy will it break in that spot again if its flexed?

  4. Hello, the video is just amazing! But i have a question – How can i fill in PlastiFix to the 0.5cm holes in motorcycle parts? For example: My motorcycle has holes made by a screwdriver. – Thank you!!!
