You speak of many different issues but you keep bringing up the advertisent regarding the matching. Just who is advertising this?
You then have your damaged garage doors you want to repair. That apparently a completely seperate issue. The company is not required to repair damage you caused nor are they required to provide the process details, materials, or material codes to you to allow you to do it. If you want to compare the moss magnuson act to your situation, compare it in like terms: do you think the car manufacturer must provide paint, their paint process, or the materials to you? That would be a more accurate comparison.
So, what is your actual problem you think the law can help you with?
