About Coast Guard color

[Eastrock]

Hi guys, need your help regarding the coast guard color. which is best the universal orange or the chevy engine red?

both paints are hard to find in my location, If I use Tamiya acrylic what ratio do I have to mix, when Orange is the Main color? read from the other forums that its a bit of reddish international orange, problem is what is the closest color of international orange, before I could drop a few red paint.

Thanks a lot!!!
