Kneadatite putty to mount PE parts
You can use Kneadatite or Duro putty to mount PE parts. It's easier than superglue for some bits as it remains slightly flexible.
Kneadatite comes on a ribbon, so you can slice a small bit and mix this up. I used a toothpick moistend in alcohol to place a blob of putty where the PE light guard had to go. You can then use the putty to mimic the weld bead.
