How to FadeIn 3dObject using alpha color?

Question

Hello everyone I know this question was asked a multiple times, but non of the solutions from other question gived me a result I want.

Here is the code example that I tried first, it changes the value of RGBA but it's not returning them to material, basically I don't understand how to return "Color" to material.

 Color col = GetComponent<MeshRenderer>().material.color;
 col.a = 0.4f;
 Debug.Log(col.ToString());

And a second example just gives me a material error.

 Renderer rend = GetComponent<Renderer>()
 rend.material.SetColor("_SpecColor", new Color(1, 1, 1, 0.5f));

Anyone can you please give some advice.

Sorry for double question, found the way of doing it. in answer of @joe_bar from this question: http://answers.unity3d.com/questions/60453/fading-out-using-rendermaterialcolora-doesnt-work.html

Here is the code excample that worked for me:

 Renderer rend = GetComponent<Renderer>();
 rend.material.color -= new Color(0, 0, 0, 0.9f);

Sorry for self answering.

Adding one more thing for those who going to use it in "for" loop use it with double.

 for (double i = 0; i < 1.0;)
 {
 i = i - 0.1;
 float a = (float)i;
 GetComponent<Renderer>().material.color = new Color(1, 1, 1, a);
 }

Then it will work properly.

Also to FadeOut use it like this this from my Corrutine: GetComponent().material.color = new Color(1, 1, 1, colConv);
