How do I seal/fill holes drilled in plastic topcase?

[BrianT]

 

I transfered my old Givi topcase from the old GT to the new GT. The mount system is very different and places it much closer to my passenger. Because it's so close I had to remove the back pad that was drilled into the topcase.

 

This leaves me with two holes that obviously need to be sealed water tight so the topcase doesn't fill up in the rain. Being as I'm not very mechanically inclined I'm sure someone out there knows a good way to do this. Any suggestions on filling/sealing the two drill holes in plastic permanently?

I'm sure others will chime in with an appropriate filler material to handle this, but in the mean time, you may consider finding an appropriate size nut and bolt and sealing with silicone adhesive.

I know we recommend this often enough to make it seem as if we own stock but we don't. We're just very happy users of Plastex. You can patch, fill or mold parts with this stuff. Check out the tupperware repair here.

The issue I think you may encounter with a plastic filler is the lack of a backing. Plastex may work, but I wonder if the plug might be likely to just push through. Some sort of backing material might be necessary.

 

I think the easiest thing, if you don't mind the appearance, would be to use a couple of plastic automotive panel clips To ensure they were totally waterproof, I'd put a little silicone sealer on the back of them, then just press them into the holes--they have circular gripping rings on the posts and will stay in place forever. You can get these at any automotive supply store:

Great idea Mike!

JB Weld is another option.

Mike ya beat me too it. it'll look fine, can be sealed by putting glue on the under side before inserting and is a quick fix. I've used this method on my dash.

[Sidmariner]

Agree completely. I did the same thing on my top-case using those plugs. I have the option of replacing the back-pad in the future without re-drilling holes.

Did the same thing - pulled the Givi back pad on a trip as it was pushing Peanut too far forward. How to deal with those holes?

 

Peanut figured out a roadside cure: foam earplugs! Perfect fit.

 

OK, not the permanent fix you were looking for, but they kept the rain out!

Thanks for the quick replies everyone. I picked up some of these fasteners and some silicone sealant. Hopefully it does the trick.

Eff, when I saw you name here some how I knew your fix would involve reflective tape
