20 oz Rust-Oleum 7585838 Cold Gray Professional Galvanizing Compound Spray

Same product as what the box stores carry which is a great product but much more affordable on Amazon

A very nice spraying paint that dries quickly. However, in my opinion it does not look like cold galvanizing, it looks like a semi flat gray paint.

Used on my galvanized trailer. Had a piece welded back on and primarily use the boat in saltwater. It's holding up great

It smells really bad

Used on gas exhaust cover on the roof. Was recommended for galvanized steel and application where item would be heated from sun and furnace. Was able to spray it on even in a heavy wind, with minimal dripping. Coating looked identical to other exhaust covers that were professionally installed previously and have exhibited longevity.

Best to have a project to use the whole can in one session to avoid clogging.

zinc has suited me well for many years. yes its paintable make sure its fully dry to prevent cracking.

I bought a 1999 boat and trailer and the trailer had few rust spots that I wanted to address. I removed the rust, applied loctite rust dissolver and applied several coats of the galvanized compound. It is easy to spray and dries quickly. Maybe I did not let it dry long enough but putting the parts together left some marks on the paint, but that could be user error. I will do some tough up, once I have everything back together. I also painted the galvanized rims that were a little tatty... They now look a lot better. One thing that I did not like was the fact that the paint in uniform in color and very dull but it beats rust, so I am happy.
