Ok, I guess you have a steel bridge deck?

I use Ameron products sold by PPG. I presume they are available in Montreal. I've bought them in Newfoundland.

Base coat is Ameron 302 zinc primer. Overcoat with 235 Bar Rust. Several coats.

This is two part epoxy paint. You can mix less than one gallon portions and the stuff keeps pretty good. Can even freeze in the can. Best to get a respirator made for dealing with the paints. Buy it from the same dealer who sells the paint to make sure you get the right cartridges.

The vapors CAN give you lung damage. But safe enough if you use normal precautions.

I work on steel ships and can tell you that the length of service is dependent on your quality of prep; it's got to be perfect and followed up with following your paint manufacturers tech advise on coating dry film thickness per coat and overall finished thickness. 2part epoxies give the best service life by far. If your time underway with bathing your hull and deck in saltwater is limited, the finish will last a long time. With high miles like 30,000/yr or more we get 3 yrs.

I did heard a paint call ferrox and they seal it with a varnish primer it is suppose to be good for 8 years in salt water

Having owned a couple, I can tell you prep is everything. It is not practical to sandblast rust areas since it would dust all the boats around it in a marina. I use to clean the area to bare metal. Use an inhibitor, then use strontium chromate epoxy, followed by LPU or a good single part enamel. I'm not even sure chromates are legal anymore. Back in the 70's we used epoxy coal tar.

I do my blasting on the swing mooring using a petrol powered compressor.
