Thanks Kevin and Jeremy for your comments.
I have used B&W before for some blasting and I found their work was good (and reasonably priced). I might try the U-blast in Langley, since warping these parts would seem awfully difficult (compared to a thin door), even an amateur like me should be able to do it
. I do intend on getting a bunch of stuff done at the same time. I have all four backing plates, rear axle, drums, torsion bar and front spindles to name a few. I have read a few articles on powder coat vs spray on. It seems like you do get a more "original" look with spray on at the expense of durability. So since this is not going to be a daily driver, I may go with spray on paint.
Phil.
