Not sure if its been covered before on this forum. My background leans towards open desert off-road racing and there is a product I've used on my cars that sprays from a spray can and is just as strong as powdercoating for a fraction of the cost. The product is called "Steel-it coatings". Another advantage to it is it can be welded on directly, without having to strip it first.
Just thought I could inform someone who wasn't aware of this stuff that can use it that wants something better than spray paint and not as spendy as powdercoating for their chassis, suspension...whatever.
