For the medium scratches I used 400 grade sandpaper.For the deepest scratches, I used 80 grade sandpaper, which is very coarse.I made three levels of scratches on an automobile door panel: In the second video, we tried another experiment using various levels of shallow scratches to determine whether or not WD40 would actually remove scratches in an automobile paint job. That’s why I made a second video to prove conclusively that WD40 cannot remove scratches from paint. This video demonstrated that it is not possible to actually remove scratches from paint using WD40 however, I got feedback saying that the reason the experiment did not work was that the scratches were too deep. If you drive in the rain, the WD40 will wash off and the scratches will be revealed.Īfter I clued my audience into the fact that the process is a hoax, I showed that the WD40 could easily be removed and the scratches remained. This process looks good, but as I revealed, it is a hoax! You should not try to do this because it is obviously dangerous (and damaging to your paint) and it doesn’t really remove scratches. In this video I showed that you can improve the appearance of scratches on your paint job by cleaning the surface thoroughly, spraying with WD40 and then spraying WD40 through a flame to “re-seal and remove” scratches. I recently made a video about whether or not it is possible to remove scratches from a car using WD40. What You Need To Know About Hiding Scratches On Your Car Using WD40
