The aestethic aspect is less important than the rust that it's not only bad to see ,but will corrode the steel structure and cause of damages and not rarely victims. First protect the steeel against rust and then paint .Acting like that we get the double effect : aesthetic and protection for a safe and longer cycle of life

Mario, I don't think Rick and Richard were saying forego the protection, but rather that there are challenges over and above protecting the surface. Generally, the client hires you to protect the asset with a coating. The expectation is that when you are done, it'll look presentable and carry out its protective function. If a client had a tank with the mismatched coating job like the green tank in the article, I'd be hearing about it. It may protect the steel just fine, but the client would be upset and consider the work a failure.

Excellent article.Color selection is frequently made by folks who have no knowledge of coating technology and sometimes as a afterthought.In the corporate environment, marketing will become involved and select colors which are based on printing inks used on marketing material. Professional applicators and coating manufacturers should certainly voice their thoughts and knowledge as there are major issues that I would focus on, the fact that the base tinting system commonly used are based on general purpose use and the ratios of colorant and vehicle added to the base coating and based on the color, can have deleterious affect on both color retention and durability. All parties should insist the coating is manufactured as a production batch which will ensure uniform color, especially on large projects where multiple trades and coating applicators are involved .Most coating manufacturers are able to produce non fugitive, gloss retaining, colors at a cost providing they know the expectation and the environment of the exposure prior to the work commencement. Unfortunately in cases where color has become an issue it is always months after the potential problem should have been addressed .
