The frame I picked up as a project for my dad has a full chrome fork and seat/chain stays. Unfortunately the chome is pitted and much of it is flaking away, as you can see in the pictures below.

Now I was aware of this problem when I got the frame, but I have another repair that will require repainting, so I am planning on having the frame powder coated. The chome that is left isn't flaking off when scrubbed with steel wool.

For those who have had frames powder coated before, will sandblasting be an option to prep this condition for powder coating or will I need to remove it some other way?
