I agree it may be cheaper to go to a blast shop. And that's what I would do.
I think proper coatings on chassis, trailers, etc., are out of scope of the home workshop
But if you are going to do it at home, and some people want just that, a bristle blaster is the only portable hand tools that will give you a profile on the steel.
The rest wire wheels, sandpaper all polish the surface which whilst it cleans the rust off makes coating adhesion worse by reducing effective surface area.
I cant argue with you on the price, they are overpriced relative to normal power tools, but they do work and that is why we use them.
Profile =Coating adhesion = long coating life.

It probably is, but at $50/day from Kennards I’ve just discovered a new tool to try at some point. I was going to buy a needle scaler, but these look much better for large areas.Quote:

Blasting is normally 75-125 using garnet.
All other hand power tools wire brushes actually polish the steel which i the last thing you want for a tough adherent coating.
