Need Help with Acid washing BID

I’m looking at bidding a fleet of 53’ aluminum rock trailers. Light to moderate oxidation. I believe an acid wash with brush would be the most effective. Whats everyone’s thoughts on pricing? Midwest for reference. I just don’t want to bid too high. If I’m in the ballpark of the other companies, I’ll get the contract based on the referring party.

Its hard to say. I dont think alot of people do fleets on here and the market varies quite a bit. You’re prob better off calling a few companies in your area to get the info you need.
