Are you planning to apply polyester to a porous surface? Then use the G4 Bonding Layer. The G4 Primer or bonding coat is an ultra-thin primer that is suitable as a base coat for impregnation of all cold-curing plastics (except epoxy).

Is your plastic or wooden project ready, but do you want to protect it against weathering? Then use the G4 Sealing Coat. This protective layer is used to protect wood against moisture and rot. Or as a high-gloss varnish for wood and stone. In addition, the G4 Sealing Layer can also be used to protect metal against oxidation and rust. A few coats of G4 seal your surface against soot.
