Is your metal welding neater?1. Clean the area well with a solvent.
2. Rough the area up.
3. Cut a patch of suitable plastic. Mine was from the remains of od On/Off switch to a dead air compressor.
4. Heat mould the patch with a hit air gun and mould to suit.
5. Using the Frost Plastic welding attachment and a general rod from the kit, weld into place.
All of the above, but replace step 5 with a wide tip hot soldering iron to melt the 2 bits of plastic together.
It kinda looks like hot glue?
It's not frost at their old tricks is it?
Either way, a few pennies saved.
