I read something about we need to use non-metallic tint to coz of the navi.... is this true....

Correct. Though many people report no difficulty with using metallic tint, the fact is that there is some risk for navi inaccuracy with a metallic tint. You can use either a high-quality dyed tint like the Johnson Greystone tint I was using on my RL, or you can use ceramic.
