This uncle at the workshop examined the depth of the scratch and told me that it could not be polished off. I told him the story of my FD Civic and he also cautioned me on the possibility of “2 tone” effect should I choose to repaint the fender. He suggested that I live with the scratch mark. Before I left, he said that since my car is white, he recommended that I rub over the scratch mark with a white candle, so as to reduce the visibility. I tried that the next day, but the result was mediocre.
I believed the experiment failed because the pigmentation of the white candle was not strong enough. The idea of oil pastel struck my mind due to its wax-like texture and deeper pigmentation. I purchased a box of pentel oil pastel for $2.80 and carried out the experiment. To cut the story short, here’s the before and after photos:
The oil pastel did help to mask out the scratch mark, though not 100%. However, I am happy with the result as a paint job would cost at least $150 and there is the after-fear of “2 tone” effect.
