Couldn’t be happier with my purchase, I had a bumper and a wing to paint and top coat, after a few hard lessons and mistakes I finally have a bumper and wing that look absolutely perfect, the top coat is very simple to use, 2parts lacquer, 1 part hardener and a splash of thinner. Takesa couple of hours to harden and can be sanded after several hours, i used 400, 800, 1000, 1500, 2000, 2500, 3000, 5000 then polish and it looks like it was painted professionally!
