Great stuff!
I used this to repair a broken tab of a motorcycle body panel. It worked a treat! Easy to mix and has decent workable time. Once fully cured (that's the important bit - make sure you give it enough time to properly cure), it made a tough repair. The only issue I had was the replaceable cap - it was a bit tricky to get the right way round and I was trying hard to not contaminate the black resin with the white hardener. All fine in the end though. I got enough to last a good while now, so looking round the house for more plastic things to fix!

BMW Turbo air charge pipe fixed
Use this to bond and fill crack on turbo air charge plastic pipe on BMW, that way I saved almost 300euro on this part. Hold vibrations and boost good so far

Erg tevrede over de lijn, mengt goed en de uithardingstijd klopt ook.
Prima lijn, hard uit in de opgegeven tijd en is makkelijk te verwerken, ook de afsluitbare dop is fijn omdat je meestal maar kleine hoeveelheden gebruikt.

Amazingly strong epoxy for repairing plastic stuff
Amazing strength bonding plastic. Used it to repair the plastic hinges on my ABS tool box. Had low expectations due to the strength needed to hold the flap door together, and yet it worked so well!
