No argument here. I am not trying to take sides and I agree with your statement 100 percent.
The reason you don't see them used by professionals is that they are generally doing complete restorations and are working on cars that have been media blasted or acid dipped. Hence no rust - the correct way of doing a restoration. Rust has been cut out and panels replaced with new metal.
However a DIY’s will not have the tools skills and or the money to dip a car, cut out panels and replace them. It's simply not worth the time or money on many cars. Pro's would also refuse to work on many wrecks that DIY’s may choose to work on. And yes I have seen where pros have said that they use these products.
If the circumstances are such where one is going to use the product - then I think pre-rusting a surface to ensure the product adheres isn’t such a bad idea. Just don't let anybody use it over an entire car as I have seen people suggest!
"Go to the links provided and come back with a quote saying they used this technology."
Read the link I posted. Epoxy and moisture cured coatings are both used on bridges and oil platforms. The choice all depends on the condition of the structure, temperature, humidity, the availability of spray equipment, money etc. Again both products are used under different conditions. The technology is valid.
