There was a time when 2K high build, filler/primers didn't exist. So if you were in a situation where you needed more fill. Your choice was only, apply more body filler. Or, spray on a polyester primer.

Some guys prefer the polyester route. Usually these are hobbyists and some older restoration/custom type shops.

Some guys prefer the 2k primer filler route.

In a main stream collision shop. You will probably almost never see a polyester primer being used. It's really kind of a older carry over. Like people still spraying off brand lacquer primers.

Really the choice comes down to personal preference and quality of bodywork. If a 2k primer/filler does not have enough build. To fill the existing " significant " imperfections in a panel. Then a polyester primer maybe a better choice.

In this case when you are talking about a 2K primer/filler, is that the 2k urethane primer and not the polyester?
