Some of you might think ‘duh!’ but this was a bit of paradigm breaking for me :)
I’ve owned my car since 2001 and about 4 years after I bought it the plastic headlight lenses started to fog and craze. The situation had only worsened over time and about 18 months ago I tried an ‘over the counter’ solution from one of the box stores. It seemed simple enough, rub the lens surface lightly with their garnet paper and then brush on this clear syrupy liquid which was supposed to fill the small cracks and imperfections giving a smooth, clear surface when it dried. It didn’t work all that well.
Yesterday as I was waiting for glue to dry I finally got tired of the ugliness and went all woodworker on those lights! I opened up my kit and pondered how to proceed. Finally deciding that polishing plastic was no different than polishing out a film finish (just the ‘film’ is far thicker) I approached it accordingly. Wet sanded the lights with 400-600-1000 grit and then used a round applicator pad and butcher block oil with two grits of pumice (FF and FFFF) and rottenstone in succession. The results are visible in the picture. The left front light has been polished and the right front has not. It took about 25 minutes to get that level of clarity.. which is really almost new-car clear, the picture might not show that.. and I didn’t have to spend a dime on anything new or fancy, just things I already had in the shop. Last night I drove the car around and found that my lights produced a whiter, sharper light than they had in years. Since I’ve noticed just how many cars develop this fogged condition I thought I should share it with my fellow headlight polishers here on Lumberjocks.
-- Mistake? No, that's just an unexpected design opportunity....
