There are several things to consider when buying it.
The choice here can be very confusing. The same applies to the epoxy resin itself. There are many products on the open market and not all of them are suitable for your planned project. If this is your first try with polyester resin, we recommend that you inform yourself thoroughly about the products before you buy. Do not buy a product that is offered cheaply, but may then prove to be unsuitable. With products from good manufacturers, you are on the safe side. Otherwise, you may have to put a lot of effort into art work only to discover that the material does not harden completely.
