Did anyone use this to fix / glue broken plastic objects? It is not a glue but it is plastic that hardens with uv light.

I'm a big fan of the Wurth fix-all stuff- a little metal body tape as a backer, fill with fiX-all, let cure, re-drill the hole, good as new:

I'm using the Bondic

Works great. Be aware, however, that it will usually leave some material around the crack on the surface, and it is white.

I use Gorilla Instant Glue (in place of resin) and woven fiberglas for most plastic repairs on my cars. I have used it on the armrests to reattach the eye holes, the center console eyelets, front lower spoiler tears to name a few.

I've done plastic welding too with great results on some parts, so so on others, you just need to get the heat and filler correct for the type of plastic.

The baking soda/super glue trick is amazing. Do a search on Utube...
Essentially, the baking soda is placed first on the affected area and then super glue is applied. The super glue bonds with the baking soda and makes a tremendously strong bond. The area can also be sanded...

cheap and highly effective.

What I learned from my own small campaign to fix busted plastic on my car: The fender liners can be welded up with an ordinary soldering iron, without filler (filler would be required for anything cosmetic). The chin spoiler cannot - it decomposes before it melts, like rubber. I used fiberglass and marine epoxy to fix it.

The UV-hardened stuff is intriguing. My dentist used some on me just yesterday.

Check out Machinist Mate Atomic Glue. I haven't used it, but it looks amazing. I typically do similar to Kevin. I use fiberglass cloth and 5 minute epoxy, then paint to match. I also sometimes use 3M DP-420 Black.

I always keep some of this around:

Not for every project, but a putty like material that turns into rubber, is easy to work with and sticks to almost anything. Amongst other things I fixed a sun visor clip on my 924S with it.
No affiliation.

I came across this interesting article about using solvent to weld some plastics.

Q-Bond.

Works like the baking soda and super glue method, but the powder comes in black and grey, so better matching options.

Food coloring w/baking soda = any color...

Q-bond is great, but very expensive for colored baking soda...
just saying

You might find it interesting to investigate friction welding of plastics. Basically, you spin a short piece of 1/8" plastic rod in a Dremel or similar tool, apply the spinning rod to the crack/seam and end up with a weld bead...

FWIW, I found it invaluable to buy a collection of glues and just try them on something, before deploying them on something important.

The Bondic (with the UV light) is completely kickass in my opinion, if you are able to make the thing you are repairing a little thicker over the previous crack. You can later edit the stuff you piled on with sanding or filing and you can paint it (original color is milkish whitewish).

+1 on plastic welding, seriuosly considering getting myself a kit.
