[JRK5892]

man! for the life of me i can not get this sucker STRAIT and true... i have all these creators in the seat... i primerd it to see them a bit better... any tips or just sand sand sand! i dont want my set to look like a 14 year old kids face.... i want it SMOOOOOOOTH... should i be bondo'n more.... should i be glazing it? i am lost
here is what i mean:

I'd say bondo. What I did was use a red sharpie marker and draw circles around the low spots, and X's through the high spots. I filled the circles with bondo and then would sand down. If you hit the sharpie lines you know where to stop or if you went too far. With the X's you can just sand until they are gone. I did this on my 550 tank, it takes time but is nice case you can see your progress from layer to layer of bondo. I would go from side to side, so the bondo could harden, then flip it over and over and over untill i got it pretty smooth.

The low spots you can kinda see, you can drag your bondo putty knife over the areas to see the dips and lows. Then mark them with a sharpie and then go back and fill them with bondo.

Another way to get the high spots out is put a dusting of contrasting spray paint on it, this is called a "guide coat." you then sand lightly to see the high spots.

hope that helps.

well... what I would do, is get a can of black primer, and a can of grey primer, get a scrap of foam, and stickyspray some 60 grit to one side, shoot grey primer, wait to dry, then black primer, at first you probably won't have to do that even, you can just shoot the black. use the foam block to sand it, don't use a loose piece of sandpaper, the block will hit the high spots, and miss the low spots, and the black primer won't get touched in the low spots, so you'll see black areas that are low, fill with bondo (use dyna gold, bondo will ruin your sandpaper) using a new or well cared for plastic spreader. don't try to get an even layer of bondo, just put it on tight to the surface using the spreader in long strokes, what'll happen is the bondo will be pushed into the low areas and the spreader will sorta ride the high areas. wait for the bondo to cure, shoot primer and repeat. once you get to a point where you can sand the primer off and not have black areas, move on down through the grits to get your sanding marks out, then prime a final time

In my experience, less is more. When I made my seat, I tried to sand the fiberglass base as smooth as possible without take to much off to ruin the strength. Then I did light skim coats of bondo, sanding in between. Make sure you follow the way the lines feel under your hand as well as visually.  Looks like you have a decent amount of bondo on the seat already from the pics. If so, I would try to sand more to get it straight then add more. You don't want to be riding on a great big piece of playdoh when your finished A good primer sealer will hide the little stuff before painting. it definitely takes time, I spent a while going back and forth with mine.

I also used the dyna gold filler, much better quality then BONDO. definitely spend the few bucks extra.

From what I remember from my dad teaching me when I was a little kid, Rocketcity knows what he talking about. My dad had all sorts of wood shapes he made and used to sand with, and he always used a sanding block like they sell at auto parts stores. It's like a big piece of rubber that holds th sand paper.

i got it rocking and rolling... went and got about 100 bucks worth of blocks and paper... have only used about 3 dollars worth so far! hell ya, returning this shiz!!!! coming out GREAT!
