    yes, you need to sand the clear before you buff it. as far as what compound is better… I prefer Meguirs 105

    1. You don’t need to colour sand unless you want a show car finish,
    or denibbing (sanding dirt nibs out).
    If your wanting a show car finish you’ll have needed to put 3-4 wet coats of
    clear on or else you’ll burn through the clear when buffing
    or get delamination problems down the track.

    2. Yes you can buff without sanding but it won’t make the biggest difference
    unless you spend a lot of time on it and know what your doing.
    You should just check out Autopia.org for threads on how to buff.

    3. I’m guessing fast cut is a coarse compound while extra cut is coarser.
    G3 may be the finest compound of all 3.
    The finer the less work you’ll need to do to fix swirl marks
    but the longer it’ll take to get the finish you want. Tip is to always start with finer
    before coarse, then work your way from there to see what works.

    well if he just sprayed the clear, no amount of buffing is gonna make it look better unless it gets sanded. its not like its old paint he is looking to restore.
    also color sanding is not olny for show car finishes. Some people can apply clear with a grapefruit texture and color sanding helps to smooth it out to match existing finishes

    Why would you buff fresh clear witout sanding? its not lacour.. :p
    all you would achive is chancing swirl marks in the finish, which you dont want.
    cut it with 15oo than 3000, compound than polish the swirlmarks. I use the 3M polishing system but i have heard the Farecla total is a great one step compound/polish. I am looking forward to trying it
