For those who don't know, it is an iron putty in liquid form, just a bit better, and it is used quite a lot abroad so that paints last for years on iron with the stages of paint they apply, especially when there is a lot of humidity but also for a better result when there are slight dents or scratches (of course, we always do the process, that is: sanding - cleaning and then applying to get a good result).
TIP: Once the Iron Putty Spray has dried well, we lightly sand it with fine sandpaper and then paint to get a very good result gradually.
Quite good and it is mainly for surfaces that are slightly scratched or scored, and instead of using Iron Putty, you just apply 1 to 2 coats with the spray as if you are painting, of course not fixed in one spot. You do this when you want the surface to be smooth before painting it with the final color and so that no scratches are visible and for slightly deeper dents (very small, 2-3 coats).
Update: Be careful if it is cold and the spray is cold, you will have some difficulty, so leave it in the sun to warm up for 5-10 minutes only; if it is very cold, then carefully leave it somewhere warm (not next to or above the radiator or any other heating device).
Extra information: You can also use it on wood as long as you have sanded it and if the wood is not in the best condition, meaning as much as you sand it the ugly marks don't go away and you want to paint it with another color (e.g. you want to make it white). But first, the wood must be dried very well and then you spray it for a better result and once it dries, sand and then paint with the color you want.

Everything that has been painted has lasted for years, personally I leave it for up to 2 days, then I start the preparation (light sanding - cleaning) and then primer painting and then color, quite a good job on an iron door when water passes underneath so that it withstands all weather conditions (there you need good cleaning from rust and then apply)
