Where can you find a metal coat on SS?

Question

I kinda want a Steelix but the only thing between me and that Steelix is getting a metal coat.

Answer 1

After you beat the elite four and lance the game will give credits to the creators and the game will restart.
you will be in your room as in the other games and your mom says proffesor elm wants something, you will get the ticket to the boat in Olivine City wich goes to kanto, after you play hide and seek with the girl her grandpa will give you a metal coat as a thank you for playing with her.
