Primer is a 1K ready for use primer/filler in an aerosol. It is used for priming uneven surfaces before top coating.
Primer is capable of producing a coating of a film thickness similar to that of a spray gun applied primer. The convenience of using a high build primer in an aerosol means that masking is kept to a minimum.
Mixing paint and cleaning spray equipment are avoided leading to savings in time and materials.
Primer is chromate free and easy to sand.
