hey guys, i have a skills usa competition for auto body and collision repair on thursday in green bay at the college. in the competition they give us a dented fender, we pound it out, and glaze it. i just have some last minute questions that i think i know but i thought i would ask just to make sure. once i add the glaze, what is the first thing is use to start shaping it? what grit sandpaper and with a block or no? and the last grit i hit it with is 180 i think. and the reason i ask if i use a sanding block is becasue its going to be on a curved sufface so i dont know if i use a block on not. thanks guys

80 grit WITH the sanding block. finish off with 180 - 220 grit.

Make sure you feather every edge of the glaze to it's nice and smooth.
I like to chop it down with 80, work the edges so there's a high in the middle. Then I smooth it all out with 180-220. Be sure all the lower grit sand scratches are out. You should check to see what the highest allowable grit allowed. You might be able to get away with 320, which will feel lovely to the judges hand.:D Good luck.

If you want to level it quickly you can use a cheesegrater blade then 36/40 grit then 80 then 180. The cheese grater blade is used when the filler is still a little soft, pull it toward you and the filler will level quickly.

Using a sanding block on a curved surface you want to sand along and around the surface at the same time. This means that you should sand at an angle \\\\\\\ then in the other direction /////// and you could use a slightly flexible block like the Dura-Blocks after you get to the 80 grit stage.
