well..
well, if you do 28% all around, it will be beter because 15% is barely visible at night.. and let me tell you, i had 10% all around my car.. well.. my old car for that matter.. it was still as hot during the day, jsut as dark as night on the inside.. What i suggest doing is 28% all around.. But if you want the darker on the back, and lighter on front, it wont matter, becuase from the outside, it will all be black.
