I have bumpers that need to be rechromed but are very straight to start with no dents, extra holes, or just flat bent up in places.
If by rough you mean bumpers with no rust, or with flaking chrome, then I don't think I have any.
Where are you located? It may be easier to find someone close that can help you out without having to pay all of that shipping...
