What is an Epoxy Primer?
To put it simply, it’s a type of sealer or filler that can be applied to a wide range of surfaces for protection or to fill in imperfections. For instance, it’s typically used on cars and boats to fill in dents, cracks, and rust and to offer a long-lasting, non-porous smooth finish with anti-corrosion properties. This finished surface is solid and very hard, so it can be sanded with a sander for an ultra-smooth finish that is easy to paint. Speaking of paint, with a quality epoxy primer, you can paint your vehicle more uniformly (as all dents and cracks are smoothed out), resulting in a better-looking and more professional paint job. Also, a good-quality epoxy primer provides durable protection that doesn’t degrade over time (at least nowhere near as fast as the surfaces would degrade without a primer).
