    I'd start with 60, to get the shape and use some Matt black as a guide coat, get it all level with 60, then use some ultra fine body filler, make sure it is well stirred, sand that with 120 then 180 followed by a good couple of coats of 2k high build primer, if not more, then re guide coat and block out with 180, then 320, followed by 600 then 800 then base coat.
    I'm just doing the tailgate, rear 1/4 and bumper on my wife's car, way too many contours to deal with, so as l know it's not always straight forward, but it can be very rewarding.

    I finish filler with 180. 3-4 coats of high build primer.
    then as said above block primer with 320.
    Sometimes I use Powder guide coat if doing a silver. Da with soft pad 400-500. Until all 320 scratch marks are gone. Stopper if any pinholes and nib off, but if using a fine finishing filler shouldn’t need it. clean ready for base.
    All rubbing down is dry flat with those grades.

    For private jobs at home, my electric da saves my commpressor running constantly.
    Expensive bit of kit but worth it.

    DBSV8, yes, great videos, if only it was as easy as he makes it out to be, but that's years of experience, credit where credit is due, but even he puts on at least 6 coats of primer.
    For me to do a rear 1/4, probably a day !!!!????

    Spraying that many coats in workshop and not in a booth. He wouldn’t last the day at my place. Haha.
    Health n safety?
    Also covering close by cars in primer overspray. Tut tut.
    But every shop is different I guess.
    As long as the jobs right in the end.
    Still a nice job is a nice job so credit him on that.

    I have always used the courser grit to start and rough out the shape of what I’m after. I don’t have all the equipment that a pro would have and the courser the grit the easier it is to sand. I use 40 for fibre glass (kitty hair) then 80 for filler upping the grade the closer I get to the shape Im after and the type of filler I’m using. By the time I’ve got the panel filled and rubbed down Im 7023201A-1752-4351-B9CF-E47EF4831A1D.jpeg at 240 and then it’s high build primer and the 400 and 600 prior to paint. Take your time and you get there.
