![]() Unclog the disc by removing and flexing it between your fingers to remove the resin dust.You will know if your disc is clogged if you can see circular scratches forming on the resin which look like pigtails.Regularly check the discs for clogging and remove and unclog the discs as needed.we'll explain the reason for this in the next step Use a marker pen between each pass to put some random marks on the resin.Each grit level takes approximately 10 minutes.We completed between 5 and 7 passes with each grit (as shown in the tutorial).Each movement should overlap the previous move to ensure the surface is sanded evenly.Sanding from left to right with an overlap and working down the length of the part AND then sanding vertically top to bottom.The most important thing to remember is that you sand off enough surface material at each grit stage, by completing enough passes with each grit in the correct way. If the surface only has minor scratches or surface defects you may be able to start off with an 800 grit abrasive If the surface is very rough (ie: machine routed) you will need to start off at the coarsest grit - 120. The technique is pretty much identical regardless of the project, however the starting grit can vary depending on how rough your starting surface is. Often it is only later in the sanding and polishing process that the shortfalls show through so using a good method from the start will save you time later on. Without the systematic and consistent method, it is all too easy to miss steps and undo all your hard work on previous stages. The single most important aspect with sanding and polishing is to be consistent and systematic in your approach.
