Meguiars G10307 7 Oz ScratchX

DO NOT believe the negative reviews! This cream is a miracle. Fortunately, I followed the advice of the guy who said just go at it with a lot of pressure, for a long time, until your arms fall off. It was true, and it worked. After 6 years of no scratches, dents, or dings, a neighbor kid scratched their bike across the front fender. Fortunately it was a clear coat scratch. It could be felt with a finger nail, but just barely. You don't want to be using this on a scratch that goes through the clear coat. In order to test, wipe some water across the scratch. If it mostly disappears until the water dries away, it is a clear coat scratch. If you can still see the line with the water on it, you are at the next level. Follow the instructions, put a dime size spot on a microfiber car cloth, and rub VERY VERY hard, perpendicular to the scratch, or in small circles. Do not stay in one spot for too long, keep moving. You will barely see any change at all. You have to keep doing it and keep doing it. And keep doing it. If it is a small area, you can do it by hand, for 5 or 10 minutes. I had an 8" scratch so I decided to take the risk and use a foam buffing pad on my cordless DeWalt drill. I applied the cream all around the edge, and attacked the scratch with the edge of the pad so that I could limit the area that was being affected. I worked back and forth 2 or 3 times, then gave it a rest. Did it again, then re-applied and went at it some more. Sprayed with some soapy water and cleaned it off every few times with another microfiber cloth, and dried with a 3rd cloth. Or sprayed with the hose to cool down the area. I used the firmest pad on the drill, and gave it a little pressure, until about when the pad edge was 1/2 compressed - no more, preferably less. I did this for about 30 minutes for more. So you can imagine that would be nearly impossible by hand. Just let the cream do its work, micron by micron. Be very careful to keep moving and don't stay on a spot too long. Inspect often. I got too enthusiastic at the end, trying to get the last bit, and I burned the clear coat in a small spot, which is now lighter that the rest. I don't think it went through the clear coat, just "burned" the finish. You can see in the photos, the scratch went across most the photo. In the "after" photo, you can see the small chip at the left end of the scratch, which was too deep, and the clear coat burn spot at the right which was the other end of the scratch... and NOTHING in between!! (The slight diamond pattern on the surface is a reflection of the porch lattice.) If you look at it really close, at an angle, you can see the slightest indentation line where most the scratch was, but it is very very very slight, and smooth, so the light will never catch it. Take it slow and patient to avoid the clear coat burn. Finish off by putting a few coats of wax to protect the area, since the clear coat is now a bit thinner in that area. If you are using this to remove all those fingernail scratches and marks behind the door handle, you can just vigorously rub the area a few times, and see instant results.
