Currently I am working away on restoring my front suspension/steering pieces and in the process of painting those, ie steering gear box, strut bars, control valve, steering linkages, etc. I have been using Eastwood for spray paint products and have been very happy with their overall finished quality and application. Now with regards to my question, Eastwood produces two types of gray, a spray gray and a detail gray. Spray gray is a little darker than the detail gray. Which one of the two should I be using for the steering pieces and what have you guys used in the past for product?
