Sorry if I sounded blunt but I can't help with the advances in technology since I closed the doors on my business.
The rate at which plastics develop is phenomenal and new advancements are made everyday in many fields.
My best advise for you is to try for yourself and see how you get on with experimental materials and methods of applying them.
Bare in mind what I have said about joining plastic, I take no pleasure in seeing things go wrong.
My concerns as mentioned above are for Woody and his good name in something I can see may fail.
No not may, will in time.
Some bright spark will now show a pen they made 15 years ago and is still intact, good luck to them.
Put it on a radiator or the car dashboard and watch it fall apart.
