Has some transparency

I have this OpenGL initialization code:

	glPolygonMode(GL_FRONT_AND_BACK, GL_FILL);
	glBlendFunc (GL_SRC_ALPHA, GL_ONE);
	glEnable(GL_BLEND);
	glEnable(GL_LINE_SMOOTH);
	
	glEnable (GL_DEPTH_TEST);
        glEnable (GL_LIGHT0);
        glEnable(GL_LIGHTING);
	glEnable (GL_COLOR_MATERIAL);
	glColorMaterial (GL_FRONT_AND_BACK, GL_AMBIENT_AND_DIFFUSE);
	
        GLfloat mat_specular[] = { 1.0, 1.0, 1.0, 1.0 };
        GLfloat mat_shininess[] = { 100.0 };
	GLfloat light_position[] = { 1.0, 1.0, 1.0, 0.0 };
	
    glMaterialfv(GL_FRONT, GL_SPECULAR, mat_specular);
    glMaterialfv(GL_FRONT, GL_SHININESS, mat_shininess);      
    glLightfv(GL_LIGHT0, GL_POSITION, light_position);

This is in my drawing method:

	glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT);
	glMatrixMode(GL_MODELVIEW);
	glLoadIdentity();
	GLfloat light_position[] = { 1.0, 1.0, 1.0, 0.0 };
	glLightfv(GL_LIGHT0, GL_POSITION, light_position);
	glRotatef(rot, viewAspect*0.5, size.height*0.5, 0.0);

The model has some transparency. What is the problem?

Try instead to use :
glBlendFunc(GL_ONE, GL_ONE_MINUS_SRC_ALPHA); // for premultiplied alpha
or
glBlendFunc(GL_SRC_ALPHA, GL_ONE_MINUS_SRC_ALPHA); // for classic blending

Those did not work. Could you compile my code to see what I mean.
