The '07GT 'vert that we bought a few months back has some pretty severe scratches all over the hood and a couple of other places. They do not appear to be through the clear into the color, but they are bad. My pickup is a 2009 and about the same color blue and it has some major scratches on it near the bed, so it became the guinea pig. Well, I'm cheap and I don't want to pay someone a ton of money to fix them. After a great deal of research, I decided it was time to put up or shutup. I had a porter cable on order, but decided that I was going to take the chance with my '09 and see if I could do this junkyard style on the cheap with off the shelf junk. I know this is going to fly in the face of most of the stuff I've read here on the forums, but I'll let the results speak for themselves. Most threads and videos advise high end products and while I didnt skimp on the chemicals, I definitely was budget with my tools. I spent a lot of time watching junkman2000's videos on youtube and time and again he stresses technique trumps tools. I believe him now.
I am sharing this information and am not condoning nor recommending that you do this at home or anywhere else. If you choose to do this, the risk is 100% yours alone.
I used a Craftsman 10" buffer/polisher, terry cloth bonnets and Meguiars professional line chemicals. Also, I couldn't find a full pack of 2500 grit sandpaper, so I started with the 3000 grit sandpaper similar to the stuff junkman used on that blue lamborghini on youtube. I of course didnt have a sanding block, so I rolled and folded the 3000 grit so it essentially ended up feeling like it had a block behind it with even pressure.
Here's the first two pics of the scratches on the passenger side of the bed above the wheel well. This is before washing the area.
Area washed clean
Same area, after having been thoroughly washed and after having wet sanded out the scratches with the 3000 grit and area is wet. I've filled the bucket with cold water and have been soaking the 3000 grit for about 5 mins, then I used the sandpaper, keeping it very very wet (like washing/wringing in bucket) about every 10-15 strokes. Using light pressure and as even as possible, I went across the scratches horizontally since they were vertical. If you watch junkman's video on the lambo, you'll see it...you end up with milky looking water coming off. That's the clear coat. Being gentle, I kept at it until I could see no trace of the scratches anymore (the white against the blue paint.) (by hand)
Then I wiped it off and was left with this. (by hand)
Now at this point...I am literally about to crap myself thinking "what in the holy mother of god am I doing????" I mean...I'm scared. Like, I am going to have to have this repainted at great expense and rear chewing from my wife. Then I took a deep breath, masked the area off so I knew where the damage was hoping it would magically disappear.
This is after the first time I hit it with the medium cut Meguiars. (with buffer)
Then a second time... (with buffer)
Now the fine cut (2 passes) (with buffer)
Then machine polish (with buffer)
Pulled the masking tape, hit it with hand type polish and then carnuba wax (by hand) and I gotta say, I am completely satisfied.
I have some more scratches I can practice on with the pickup and my sister in law is bringing her F150 over for me to work on her tailgate so I should be getting pretty good at fixing scratches like this. It was nerve racking at times, but I really enjoyed doing it and totally love the results. I did it on the cheap which also makes me pretty happy.
I'm really thankful to junkman2000 on youtube for his sharing of knowledge and thank you to all the guys here on the forums willing to share as well.
