Across the highway from the track and behind the car dealer is a powercoating place. The name skips my mind right now but they did a great job for us last year and the cost was right. They also use simpson sandblasting so maybe they can do the whole job for you like they did us. Hope this helps
DENCO -636-933-0899 Dennis Russel Does a nice job and is a car guy, have had him do my industrial fabrication powder-coating and have never had any complaints.
Not sure where you are located but if you are on the Illinois side of the river then i would say to try calling Cobra powdercoating and sandblasting. I think they are in Aviston. I may be wrong but almost positive. I have herd alot of good about them.
cobra powder coating in aviston just got done with alot of my stuff. they are amazing. ask for bradon or derek. thats the owner. they will treat you right
