I am finally just about ready to redo my front end and subrame. I have my Eastwood powder coating kit for all the cast iron grey for the calipers, steering links, etc. I have the Caswell zinc/cadmium kit for the backing plates, caliper brackets and brake line brackets, etc. The only thing I am unsure of is the black oxide for the bolts and tie rod sleeves, etc. What is available for redoing the black oxide on metal? I have looked at some things, but obviously, the guys selling this stuff are going to tell me how great it is. I would like to hear from guys that have used or have seen the results of a product and can honestly recommend a product.
So, what do you guys recommend for black oxide?
