yeah, I just cleaned and scuffed the paint and taped off the sunroof. I rolled the first coat Saturday morning. I didn't start early enough and it started to dry as I was rolling it on. i sanded the parts you can see beyond the roof rack and applied the second coat Monday morning at 6. the cooler temp and rolling over the first coat made it much easier. i rolled the 2nd coat much thicker too. it is hard enough to sand without gumming up the paper, but soft enough, 320 grit knocks down the texture left by the roller. i used sponge rolls. not sure if a different material roller would have worked better or worse. all in all, probably 2.5 hrs for prep and two coats. one can will do 2 cars. the website says pigment can be added to color match, so I'm thinking about adding silver and coating the wife's gx470. the improvement in rear ac is just awesome.
