Seam Line Removal, 101

Sand away until the glue has gone and the seam cannot be felt when you rub your fingernail against it (sometimes seams can be still seen but are properly filled in). You might notice that the sanding has damaged the part a little. Don't worry as this will be fixed in the next step.






Take a finer grit (1200/1800x) sandpaper and sand the same part again until smooth. The ultra-fine abrasives will buff out most of the deeper scratches made from the initial sanding.

Below is a picture of what my piece ended up like. You will notice that there are still a few light scratches from the first round of sanding. Once primer is applied, it will fill these scratches and they will disappear from view altogether.
