Plast-Aid Fix
« on: August 03, 2019, 09:58:54 AM »
About four years ago while removing the side panel cover in some fairly cold weather the tab on the side panel broke and I fixed it with Plast-Aid.  A couple of weeks ago it broke again from age so it was time to do it again.  I do have an extra side panel cover but don’t feel like having it painted and this is in such a hidden area that it works for me, and it isn’t a real Lemans I, just my commuter bike

My first attempt didn’t work, waited too long and it hardened before formed so I tried again with a more liquid application.





I used a piece of duct tape as a platform to create the tab which was easily removed once the plastic hardened, then it was just some sanding to create the tab end. The last time I purchased this product it came in some tiny bottles, but this time I purchased the larger kit on eBay for $26 bucks plus shipping.

The bike is due for a major re-paint and I’ll use one of the newer non-broken side panel covers sitting in the garage and hang this one up, but in the meantime it’s just fine from five feet away.

I once reenforced a tab like that bay epoxying a washer on the inside.

Yeah, I considered doing that too but wanted it to look reasonably close to what was there originally.

Now that's clever.  Thank you very much for an excellent workaround solution.

Thanks for taking the time to post that blackcat.  :thumb:

Reinforcing with a washer is also a good idea if there's room.

I've reinforced that type of repair with a small piece or strip of window screen. Seems to work well.

I am pretty sure that cover is made from ABS. You could also use abs glue and reinforce it from the back, with a piece of screen or better yet stainless steel mesh to add strength. You want a strong but slightly flexible repair so it wont crack in the future. I think what you used may be too rigid for that application.
  A good quality 2 part epoxy can also be used with good results.

I usually get some thin gauge aluminium and drill it like a Swiss cheese to use as re-enforcing, JB Weld that to the inside.

Thats a good idea Roy! I have done similar, using aluminum  roof flashing material, and drilling a bunch of small holes in it. I recently ordered a sheet of actual woven carbon fiber material from a boat supply place, and plan to experiment with it a little. I think it would work for  reinforcing  areas like this.

From the manufacturers literature: “It chemically fuses to many plastics such as ABS, acrylic and PVC...”  It has worked for the last four+ years.

Abs can be fused together with mek. I fused a honda pc 700 back together once.
