ABS Plastic Repair

[F6Dave]

Thanks to the crumbling pavement here in Colorado, the rear part of the front fender on my F6B has developed a crack. I've repaired similar cracks before using JB Weld Plastic Bonder, and backing up the repair with some fiberglass fabric. This has worked well enough but if anyone else has a better method please share it.

If you're thinking of riding through Colorado you might want to reconsider. Potholes are everywhere and on some roads the center seam in the asphalt has eroded so badly that passing is dangerous. I wouldn't be surprised if Venezuela has better roads.

    I've repaired an I/S saddle bag with strips of ABS plastic and ABS black hardening glue. The black ABS hardening glue can also be used as a filler and prepped and painted. RIDE SAFE.

I don’t know much about plastic repair but I’ve watched many different videos of people using superglue and baking soda.

I fiberglassed a pair of (fiberglass) Harley lowers once, from the inside.  I'd seen it done on boats.  It lasted for some years, then let go in places.  I put black duct tape over the bad spots.  Later I just took them off. 

I do not know if fiberglass fabric and resin can be used on ABS (the resin could muck up the ABS), but some kind of inside repair seems best, touching up the outside with paint?

I have repaired my IS pods several times with the black ABS glue.  I apply it from the back side, so it can't be seen from the front/outside.
Baker Airwings for the IS bolt to the pods.  In hindsight, I would never put them on an IS, but that is my own opinion.

Fiberglass rosin will not adhere to ABS. Some adhesives will hold for a little while. BLACK PLASTIC ABS glue properly applied is the best repair I have found. JB weld , Gorilla glue etc. are not in my shop for repairs to ABS.
  If possible , tape item to be repaired from outside (finished side). I have done some repairs that did not need repainting.  ABS can be used as a filler for damage repair.

I used Devcon 2 part epoxy on a LeatherLyke that fell onto the VT1100 Spirits muffler. Beware this pin system is fragile thus a zip tie might be a good safety. As for the epoxy, damn good stuff. Got lucky and it "floated" out nicely thus not bit of work afterwards. I let the new owner know as it couldn't be seen from outside and just a slight bubble inside.

 They make plastic repair tools that heat up and inbed a wire into the plastic. There is also a plastic welder set up that you feed plastic rod thru similar to mig welding steel. I have used a solder iron on the back side of my side cover to repair a crack. If you look real close you can still see it. We used to repair plastic totes this way at I shop I used to work at. The totes got serious abuse but I never saw the repair break, it was a larger iron though. My side cover has lasted over 6 years so far. I'm not sure if the side cover is the same material.
