The term 'Paint Basecoat' is a type of paint job that requires a SEALER to be applied before the basecoat. The SEALER is a protective layer that helps the basecoat adhere to the surface and prevents it from chipping or fading. The SEALER is usually applied in a thin layer and can be made from a variety of materials, such as polyurethane, epoxy, or acrylic. The SEALER is typically applied with a brush or roller and allowed to dry before the basecoat is applied. The SEALER is an important part of the paint job and should not be overlooked.
