Grill restoration company's? (pics)

Its all about money. If you want them restored may as well go total professional restore like anobrite / All Trim ? Surely you've seen their work and pricing on ebay.
If you only want to replace all the studs and may them look much better at home, it can be done. Dings can be massaged out but even those pros buff completely through the aluminum when trying to remove deep scratches.
They sell those at a discount on ebay and fail to mention the crack they made will grow. Vibration causes this and the only way to stop it is drill a small hole at both ends of the crack.
I rework my own with decent results. I admit I have bought complete grills off ebay and mix / matched pieces then stored or sold the remains.
