For those who don't know, it is an iron adhesive in liquid form, simply a little better, and it is used quite often abroad to become paint and withstand the iron over the years with the color stages they put, especially when there is enough humidity, but also for better results when there are slight dents or scratches (of course, we all always follow the process, meaning scraping, cleaning, and then applying to achieve good results).

It is quite good and mainly used for surfaces that have slight dents or scratches. Instead of using iron adhesive, you simply apply 1 or 2 layers with the spray, as if you were painting, of course not in a fixed spot. You do this when you want the surface to be smooth before painting it (once it has dried well) with the final color, and to hide any scratches or slight deep impacts (very small).

Update: Be careful if it's cold and the spray is cold, you will have some difficulty, so leave it in the sun for 5-10 minutes only to warm up a bit, if it's very cold, then be careful where you leave it, somewhere warm (not next to or on top of a radiator or any other heating source).

Extra information: You can also use it on wood if you have sanded it and if the wood is not in the best condition, meaning that the bad marks don't go away as you sand it and you want to paint it with another color, and above all, the wood must be dry when you want to spray it for better results.
