Key Repair-Step by Step Procedure


I was contacted by a member on L2D for a referral for his sister in law for a scratch repair. The car was a medium gray Corolla and had been keyed heavily down 2 doors. I quoted her a price sight unseen. She called the day before to say it had been hit on the other side by a door and had more marks in it now too.
I decided I'd do a step by step procedure for the way I repair key marks. My system works well for me. Use it; don't, at least you have one option of a way to do it.
I also decided I'd do a one step on this car using Duragloss 671. For something completely different, I decided to try the new Optimum mf finishing pad with it to see how it would work. More on that later.

WHEELS/WELLS/TIRES/WASH:

The Wheels were cleaned with Zep Citrus and a RG brush.
The tires were cleaned with OPC at 2:1
The wells were cleaned with ZC too.

The car was then foamed with DG 901 mixed with Zep Citrus. I could tell just rinsing it there was no wax on it at all but I did an aggressive wash on it anyway. Originally, I was just going to ONR the 2 doors and be done with it, but since I had to do the other side anyway, it blossomed into a full wash. It would look better this way anyway.

The car was then washed with DG 901 and power washed off. It was dried with the Master Blaster.

I then set out to start on the key repair. Here's what I was up against:

I had instructed the owner to pick up a bottle of touch up paint from the local paint supply house, which she did.
I then blobbed some onto a clean plastic lid and used a pointy toothpick to get deep down in the scratch. I put the toothpick into the scratch and leave it for a second and let the paint wick down into the crevice. I repeat if necessary. I then turn the toothpick on its side and flatten the paint out so the crevice has been completely filled. I get the paint above the surface of the crevice and higher than the surrounding area. You don't want it too high as it will really add to your wet sanding time, but you do want it somewhat higher. Here is the finished result from filling the entire scratch:

The paint was allowed to dry overnight. I finished it at about 1:30 am and didn't get back on to it until 1:00 the next day so it actually had 12 hours to dry.

The next step is wet sanding. I had taken measurements and had lots of paint to work with. I started trying to level it with 2500, then moved to 2000 and then to 1500 as it was taking so long. I would level the built-up area with 1500 and then go over it again with 2500. I went over the area one final time lightly with 3000 grit. It took about 2 hours to wet sand the area. Here's the final result of the sanding:

I then used my Dynabrade rotary with a black TufBuf wool pad and M105. It was ridiculously easy to polish out the area. I followed that up with M205 and a B & S white pad, again with the Dyna.
The night before I had decided to go over the whole car with DG 671 so it did not look goofy just having the doors polished and that's it. I started out with the Optimum mf polishing pad and my Megs DA, but it did not have enough cut for me. I then upped the pad to a white LCC and still I was not happy. I then tried a Surbuff pad with the DG 671 and it worked like a charm! I was not expecting it to, but then again, I don't have a lot of experience yet with 671. It finished down very well and really cleaned up the surface. That was used on the key repaired doors as well too.

I wanted the wheels to have some protection so I broke out my paint gun and sprayed them with Permanon Platinum. I then decided to do the whole car with it. The entire car: glass and paint was also done. This was wiped down with 2 different mf's. It was crazy slick after this step.
The tires were dressed with Opti Bond and the windshield trim done with UTTG.

I ended up charging them $50 more than I originally quoted. One look at the car and the man said he was more than happy to pay it and thanked me for the extra work.
All in all a 6 hour job.

Thanks for looking.
 
Nice job on the scratch,, I have a very deep serious key scratch to contend with myself and its good to see some possible results. I plan to use the toothpick/wet sand/polish approach as well.

With any key repair, I find the darker the colour, the easier it is to make it completely disappear, especially with metallic paint. I will be looking forward to hearing about your progress on your repair. Thanks for the comment.
 
Great job Rich! Was the scratch removed completely? Can you see it if you were up close? I have never tried touching up/sanding/buffing deep scratch out before.

Yes, completely removed...and, thanks!
 
Looks awesome! I mean no disrespect, but I have to ask: would you mind taking some head-on shots with different lighting of the repair area?

I've never seen a repair of that nature turn out quite that seamlessly, especially with a metallic color.... simply because the metallic distribution in the touch-up is usually different than the rest of the finish.
 
Hot damn Richy, another absolutely awesome repair!!! You are the repair master for sure! Great job as always buddy!!
 
I got to get a panel and try to do this.

The dg671 is better than dg501? more cleaner or more polish?

Charlie, the car is back with the customer now. I told them on the phone it wouldn't completely come out. I was surprised too to be honest with you. All I can add is that I did a lot of wet sanding on the area. That, in my opinion, is what made all the difference. I spent 2 hours wet sanding that area for goodness sake...that's a long time, considering it took me 10 minutes to polish the same area, and 6 hours to do the whole thing in total!

Thank you Tad! I was very happy with how it came out. They were a really nice couple so it was very rewarding to see their reaction!

Make sure you sand enough.

The dg671 is better than dg501? more cleaner or more polish?
Better? In what way? Both products excel in 3 areas:
1) Cleaning ability
2) Durability
3) Looks
You'd need to do some side by side testing to really see. 671 is stronger at cleaning, but beyond that, I honestly don't know as I just started playing with it myself.
 
Great Job Richy!
How would you compare the cut of 671 compared to other products you have used?

I have some on the shelf just havn't had chance to play with it yet.
 
No kidding, a Surbuf pad. I was going to be mad as heck if the white pad would have worked for you because I tried it on more than one occasion. Car looks excellent by the way. :props:

And just to note to anyone reading this, DG #671 does NOT contain fillers.
 
Amazing and thank you! Great job! I've always wondered if that could be done and turn out that good! I'm wondering did you damp sand with a machine or block sand by hand?
 
Great work!!!

Do you every add clearcoat on top of the touch up paint or do you just leave it?

I assume it would be much easier to skip the clear but is that gonna cause issues down the road?
 
Richy,

Another outstanding step by step tutorial on how to fix something we've all experienced at least on time in our lives.

There is little doubt that when the customer saw these results she may want you to have your child! :eek: :laughing:

Tremendous work Richy!! :props:
 
In all honesty I had no idea those scratches could be repaired without repainting the entire panel. What a fantastic job and the fact that I learned something from it makes it even sweeter. No doubt the owner is ecstatic over the outcome and extra steps that you took.
 
BRAVO Richy,just BRAVO-:applause::applause::applause:
