Fully understand mate. Nice obvious silver chassis has always seemed a bit like saying "take me, I'll last longer"I googled por15. Said it's for a rust prevention. As it's galvanised I just want to paint so it don't stand out.
I've used both Hammerite Special Metals primer (red) and similar stuff from Ronseal and International Paints (both white). This was on aluminium and galvanised steel. Of the 3, the Hammerite gave a better "grip" for the subsequent topcoats although I did use a brush to get it on (I'd prefer to spray). I sprayed the topcoat on one area and brushed another, and the brushed finish lasted much longer. The surfaces primed with the other 2 began to show the original surface after a year. FWIW it's the only Hammerite product I'd use again, the rest is c*ap.Think you'll find you need their 'Special Metals Primer' for Galv mate. Not sure whether Acid etch would be better?
A grown up with better options for Galv Chassis painting will be along soon?
Good, but old fashioned. Used to use that, followed by washing off, priming, undercoat and topcoats on galvanised structural steel, highway bridge parapet rails and the like. It was phased out by the mid 1990's when clients started specifying etch primer as the first stage. If it was mine I would give it a dose of chassis wax (don't want to mention w*x**l at the risk of igniting another protracted fred)Mordent wash
