That certainly looks good. I've never used 2-pack myself. The system I've used quite happily for ~12 years now is the zinc phosphate primer and on top of that a paint that the Johnstone's company refers to as "metal cladding paint", but I'd have to go back the website to see what meaning they attach to that description. It's worked well on car floors for me. All that said, I'm always looking to see if I should look at anything else, but I don't think I'll be going to 2-pack.what norsa means is the normal stonechip that you don't add an hardener to like yours dries by evaporation of solvents and although they have dried hard they can be softened/ removed if wiped with paint thinners/ petrol/ brake fluid. where as raptor 2 pack types set and are unaffected in the same way but "might" be removed if a thinners soaked rag left on the raptor coated surface. i used gravitex put on with a shutz gun on my cortina then painted in body colour synthetic paint and still seems in good condition 6 years later
The one thing that has attracted my attention recently is that the ZnP primer I've been using contains about 1% ZnP, but some companies are now offering primers with 5-10% ZnP. However, it might be a mistake to judge those paints purely on the ZnP%. I really like the way the one I have been using wets the surface of just about anything you put it - just flows on to the surface, and I think that is what you want in a primer. But, thinking of the comment above on anecdotal data, it is just a fact that mostly, people tend to stick with what they've had good results with, in the absence of other "scientific" data.
