Is there any way to lock a folder on my desktop with a code or hide it so that only someone who knows where it is can find it?
I use to get Quest pipe fittings from Lowes, but they don't carry it anymore. I would check with a mobile home dealer in your area. (note: I did my current house with Quest when I built it in 2004, and no leaks have been noticed. I used the more expensive mechanical type fittings rather than the crush on type.) If all else fails, there is copper water lines, but I recommend you use mechanical fittings rather than solder type fittings. If you use copper, you will not have problems unless they freeze up.
You are pushing the material to extremes - I wouldn't dare answer and expect the only good answer will be from the manufacturer of the materials. My experience with clear materials is that you don't have much chance of making this work and when you add durable to scratches (resin is fairly soft) and shock proof, I am even more pessimistic. If you work out a way to do it and can show good result after a couple of years, you might keep it as an artistic secret to make your fortune.
