smoothing it out

[rbohm]

what you want to do is use a guide coat to let you know where the high and low spots are. what you do is lay down your primer coat(lets say grey), then you lay down a thincoat of a contrating color, in this case black, and you sand untill you see spots of black on the grey. these are your low spots, and you can then either add a little body filler, if the spots are fairly shallow, work the base metal some more, if the spots are deep, or add more primer-filler, if the spots are real shallow. sand again using the guide coat. repeat the process untill the guide coat comes off evenly.
