After three coats of the surfacer with this thinner, the adhesion on bare metal is noticeably better and there's zero peeling even where I scuffed it thin. The 1000 mL bottle lasts a good while when you're prepping panels daily.

The 1000 mL bottle lasts through several big jobs, which is great. Mixing it with the surfacer gave me a noticeably smoother, more durable finish with zero peeling after a week of heavy use. Exactly what I needed for professional work.

Mixed a batch with the mechanical surfacer and the paint laid down noticeably smoother than with the cheap thinner I had before, no peeling on the edges after two days of drying. The 1000 mL bottle is generous too, so it’ll last me through several projects.
