one copper radiator=1000 dollars but will out last your car and will sell for scrap metal ---10 plastic radiator cost 2000 dollars but no scrap value [ all value are a estimated ]

Why not use 100% ethylene glycol solution and save some money...
The first one died at 87000. Then I drove it cross country and it developped a slow leak throw death valley. That was at about 100000. Mine were developping leaks where the plastic joined the metal. I think it's just flexing because of the different CTEs. With less extreme temperatures, it seems to be OK.
Are you talking about the end-caps? They do fail -- especially if they overheat.
Sometimes the gaskets also go.
One of the biggest problems is the upper hose connection on the end-caps. The plastic gets brittle and with the pressure of the hose clamp the connection fails.
This has been a problem with a lot of makes as the cars age -- failure is often caused when the thermostat fails and the system overheats.
I'm not sure what this product is going to achieve?
I've seen it used a fair amount in street rods with large, high compression engines in small confined spaces with limited space for radiators and airflow. Couple of guys said the best thing they ever tried.
