    So I can spray a topcoat of gelcoat and of course there is orange peel which I start sanding at about 320# grit. Last part of the project was sanded by hand, however the next area is a lot bigger and will need machinery to sand it from all Wet 320 - 400 - 600 - 800 - 1000.....

    I get confused with all the types of sanders. Looking at air sanders... not sure if I should get a one handed palm type (random orbital) or a two hander (dual action) to sand the get coat? Here's a few pictures let me know what sander you would use and why... I have an electric DA for compounding polish&wax btw...

    Is Dual Action or Random Orbital better for sanding through the various grits?

    Thanks for the reply, so the random orbital palm sander style would work well? Why do you like that one better?

    Cause that's what was recommended to me years ago and it has worked just fine.

    Palm

    The duel action are harder to keep flat on the surface.
    Duel actions claim to be both a random orbit and spin sander, but they don't do either job well.
