![]() ![]() It soaks into the pours and yellows and makes the surface. Wax? Never wax those surfaces you need to see through. (Optional) Apply a layer of Meguiars NXT wax to really shine things up.let haze.and polish off, then let wax coat harden by letting the surface dry for a couple of hours. Lightly dampen the other end of the polishing cloth and wipe off excess rubbing compound from surface.again dry with soft towel and let dry for several minutes.Ĩ. Begin to vigorously rub the compound on the surface as if you are b until product completely dissapears or drys out.apply some more and rub some more until there is a PERFECTLY clear surface or Mirror shine, flawless finish on a colored plastic.ħ. Squirt a bit on the surface and a bit on the cloth. Take out the rubbing/polishing cloth and Rubbing Compound. make sure to wash THOROUGHLY before the next step and wipe dry with a very soft cloth and give it a couple of minutes to let it air dry.Ħ. ![]() Now that you have a smooth finish that has a very light matte look.you are almost done. Make sure to complete sanding the scratches left at a specific grit before going to a higher number!!!! otherwise you'll have to go back down and resand all over.ĥ. Work your way up om 400 to 600 to 800 to 1000 to 1500 and then to 2000 if you choose. ![]() Then move back to 400 wet and use until 320 scratches are gone.Ĥ. When the scratches are gone.IMMEDIATELY clean the surface and move up to 320 grit.different direction until the 220 scratches are gone. Jump down to 220, scratch for a few seconds, check, scratch some more, check. Major scratches or plastics/resins that are exceptionally hard will require more time/effort and so starting at a lower grit sandpaper will reduce that time/effort. If no progress was made at all go to step 3a.ģa. If they are starting to soften or are even completely gone.keep sanding until they are gone. After only 15 seconds or so look at the scratch(es). With Medium to deep scratches start with 400 grit paper, wet sandpaper and surface and begin sanding in whatever way feels comfortable. If dry sanding.remember to fully dry the surface to sand for the best results.ģ. Wet sanding will cut less efficiently than dry sanding but produces a better finish and is all but required on 600 grit or higher sanding work. with plastics, BEWARE of the cutting power of sandpaper.you will be amazed how easy it is to sanddown plastics (well I guess for me coming from metals it seems amazing :p) on flat surfaces it is easier to wrap the sandpaper around a smooth wooden or hard plastic block.this gives you more leverage and can give a more uniform surface in the end on flat/square pieces. Use room temperature to cold water temps for wet sanding. To view these lines while wet simply hold surface at an angle to the light. When switching from one grit to the other.sand in a different direction (up and down, now left and right).this way you can easily gauge your progress in removing the lower grit's sand lines. When going up in grit number (finer grit) wash surface, preferably with dish soap to make sure the surface is free of lower grit particles. it is preferable to wet sand under a light stream of water which is better than simply wetting the surface and the sandpaper. sand face of entire surface, not just the scratched area.this creates a smoother finish that is free from depressions. Before we begin sanding here is some helpful tips to ensure a proper finish: Begin every project like this by cleaning the item.just use dish soap and a soft cloth, no abrasives yet.Ģ. You can perform the higher grit work with a polishing wheel/polishing compounds but it is not precise and with clear plastics/resins it is far to easy to discolor/deform/weaken by heat (also known as 'burn')ġ. Lets assume that the scratch you are working on is deep and in additioin I will provide wording that instructs how to manage minor scrapes. I removed a deep scratch from the ipod face (brand new ipod, scratched by watch during screen removal). Deep scratches ARE removable but require more work an additional materials. For removing scratches from your clear ipod viewing window/cell phone screen/and come to think of it this applies to the headlights too and any other plastic pieces that need to be smoothed out/remove scratches/prepped for painting/inbetween layer prepping for high gloss applications/clear plastics/resins (acrylics, plexiglass, lexan, lucite, etc.) such as our RX-8's stereo faceplate and headlights/tailights.įirst, make a rought determination of how deep the scratch is. ![]()
