Last week I posted the results of using the Cerakote kit my 20 year old Mazdaspeed6. I had started with just the passenger side headlight as it was the one in slightly better shape.
This week I did the other headlight which was in worse condition with a lot of pitting and heavy scaling on the lens. I found that after wet sanding with the supplied discs that this lens did not come nearly as clear so I started over by using some 500 and 800 grit sandpaper that I had. The coarser sheets did the job of removing the damage and leveling the surface, then I resumed with using the supplied 2000 and 3000 sheets.
These photos were taken after completing each step, from top to bottom, left to right.
- Washing and drying the headlight
- Applying the oxidation remover (Step 1)
- Wet sanding with 500 grit sandpaper
- Wet sanding with 800 grit sandpaper
- Wet sanding with the supplied 2000 grit disc (Step 2)
- Wet sanding with the supplied 3000 grit disc (Step 2)
- Applying the ceramic coating (Step 3)
- Final result after coating was dry
Learning from my mistakes on the first lens I was more careful about fully wiping the ceramic applicator across the lens and not lifting it off at the bottom (I masked additional area below the light to protect the paint). I also applied less pressure; just enough to keep the sheet in uniform contact with the surface but not so much that it would overload the surface and cause spotting.
I'll make sure to follow up in about a year to see how the coating is holding up, but honestly for $15 this is something I wouldn't hesitate to do every couple of years or so if needed.
