Didn't realise this was water based. 2 coats on bare steel and instantly it is rusting before my eyes. The metal had no rust before painting.

I bought this metal primer to paint my rusty metal garage, metal pipes, and rusty gates. I follow the instruction to do preparation and clean up the surface. Then, apply the metal primer with a roller and brushes. The colour, medium grey, looks good after painting. Lets see how it performs after a few weeks. The instruction of the paint do not recommend if the outdoor temperature is 10 degree or below. I do it when it is about 10 degree on sunny day.

Very happy with this product. Covers well and did a great job as an undercoat on my home gym that was showing signs of rust. Reasonably priced too!

Horrible product. Difficult to spray and work with. Terrible coverage and ended up stripping the coat and not using.
It worked fine for me! I removed the old paint with paint stripper, sanded the rest that did not came off, then I cleaned the surface. I painted with water based paint and no issues until now.
I had the exact same issue as the last review whereby but this primer rusted bare metal before my eyes within a matter of hours. Item in question had been previously painted and sanded right back the previous day - no rust before or after. Until it was primed. The entire water based range in the rust guard products is heavily misleading and more suited to craft or hobbiests. Their Rust Guard clear coat isn’t even waterproof and is for indoor or sheltered use only. Not sure about others but there’s not a lot inside my home that need protecting from rust but anyway. I also found White Knight customer service overwhelmingly unhelpful.
Good primer, however have seen better, painted a few steel beams before top coat, the product went on well, however seemed to have an extended cure time and i noticed after a week, it was prone to coming off. Could well have been my level of prep, however I had cleaned with sugar soap and a scrubbing brush so expected slightly better performance.
