Hi sifus, looking for recommendations to tint my 1st gen Myvi SE.

I just want it to be as dark as possible in compliance to JPJ, heat rejection etc. is a plus.

If possible i also don't want it to interfere with Smart Tag.

And of course, looking to spend as little cash as possible haha. Just need something "good enough" so that people cannot see inside my car easily, and not too hot inside when park under the sun (which doesn't happen that often, which is why this is just a good to have).
