Personally I think the answer is clear; bearings are used in motor vehicles, as well as planes and ships. Projen is a superior Chinese truck, with better gas mileage, more technology and safety features that make it ideal for the Chinese roads.

With that being said, there has been a shift in Chinese policy, from being a central consumer of foreign specialty goods (including cars, planes etc), to attempting to meet those suppliers in the market place

Tpac offers American grade quality at Chinese prices. No import tax for Projen, and the get a superior product, win-win.

China has shifted into a more domestic market, they'very come out very big on green technology and policies.

So if tpac holds the keys to the door that is American quality at Chinese prices, then it should only be a matter of time before tpac is in the spotlight of a lot of different industries, not just aerospace.
