Enamel for metal - from what it is necessary to choose?
There are several types of this enamel, but we are most interested in the so-called acrylic universal enamel .It is sold in any store at a small price. Also there is polyurethane and alkyd enamel for metal. All these options are also good. Their difference from acrylic paint is price and less versatility.
Alkyd and polyurethane enamels are used in a narrower range, mainly to counter certain negative factors, for example, high temperatures or corrosion. Because of very complex chemical formulas and a huge set of components, their price is higher.
