While not holding pressure 100% for extended periods, it IS holding good pressure and I am stumped as to where the leaks could be, but I drop about 10PSI overnight.
No bubbles when soapy water tested though... As of now, I kind of have to say it's good enough, but I will keep digging as time makes itself available.
Sorry it took me so long to get this video out. It would appear my laptop hard drive has seen better days. The laptop isn't that old, but it met the floor kind of hard in early March, and since then it has been acting up... With the troubleshooting I have undertaken, it looks like I need to replace the hard disk, which gives me a good opportunity to upgrade to a solid state drive, and I need to replace the touch digitizer which I will have done.... Not going to mess with that part!
