FWIW I have never tried Lankga with regular out of the bottle touch-up paint maybe it would work better with it.
I get very obsessive about touch ups on my Ferrari and even my old 911, I've never been able to find a perfect color match with the touch up bottles, they are always a shade off and its so very thin they cover badly and take forever to fill a chip.
So I use OEM paint from the code thru auto body supply shops, once I get the chip filled,sanded and buffed properly its pretty much undetectable unless under florescent lights where if you look real close you'll see a slight ring around the repair.
Getting it that way is a job in itself and frustrating, many tries are needed to get the chip filled properly and then sanded down perfect with the paint |

I use enamel touch-up paint in a bottle -- the kind you'd get at Autozone or Advance Auto. I'd have to look to see what I have in the garage, but either the Toyota or Nissan red is an almost exact match for my 1984 308QV. You can't use lacquer-based paints with Langka.
I dab it on right out of the bottle. I usually let it dry overnight, or at least all day, and then do the Langka thing right per the instructions. I've done it with shorter dry times (an hour or two) and that works but you have to be more careful -- it's much easier to take off "just the right amount" of the paint blob the next day, or at least 8 hours later (like if you touch it up in the morning, and Langka it in the evening.
The spoiler on my car has been rebuilt and repainted with 2-stage paint. Rock chips there still are invisible (unless you're *really* looking for them). The only reason to add clearcoat is if your touch-up paint is also a 2-stage paint that comes with base color and clearcoat, since the paint in that case won't have a high enough/proper gloss otherwise. Langka suggests adding the clearcoat TO the touch-up paint in that case (pre-mixing) so you don't have to add clear afterwards.

Mike,
Some questions, if you please:
What kind of paint do you use and do you have any advice on how long to let it set before using the Langka?
Do you add hardener like Jeff does?
Do you finish it off with clear coat?
Thanks!

The Langka stuff works VERY well on rock chips recently filled with touch up paint. It's pretty amazing. I have used it numerous times on my 308 in accordance with their instructions.

Marty,
If you should decide to follow Langka's instructions rather than Jeff's, please let us know how it turns out.
This stuff sounds too good to be true!

If you use THIS LINK for getting to the Langka site, they'll make a donation to the Ferrari Club if you buy anything... |

Martin,
I use OE brand paint mixed from the color code from a auto body supply, I'll also buy a cheap $6.00 small can of hardner (the Glasurit I use and only sells hardner by the gallon which is very expensive since we are just dabbing a small amount most any type hardner will do) to mix with a dab of the paint and also some thinner if it gets too thick.
The Langka is designed to work with touch up paint you get from the dealer, by using a pillow case or other tight cloth its designed to just take the touch-up off.
Since I am using OE paint it doesn't work the same way, when I've used the Langka on it it seems to take a while to get the filled chip soft and would take too much of it off or the whole amount, this even after letting it cure for a few days.
I'll fill the chip as flat as possible with the touch up using a toothpick (if the chip is real small I'll use a razor blade to cut the toothpick to a very fine point)and let it dry for a day or so, after that I would take a very small piece of 2000 grit and fold it put Langka on it and lightly sand for a few seconds, it will rapidly take off the new touch up and risk less damage to the surrounding paint since you do not need to sand as much, you can almost make the repair invisible if the paint is filled and level enough to begin with.
By using just 2000 grit alone you risk burning thru a layer of surrounding paint and you will see a ring which is impossible to fix.
You only sand with the Langka and 2000 for just a few seconds but you need to be very careful that you are just sanding the chip and its edges.
After you have used the Langka with the 2000 the chip will look dull compared to the original paint, thats where you use the 3m fine cut compound with a smooth cloth to buff the finished chip.
Let me know if I need to clarify more. |

Jeff,
the langka web site says nothing about using any sandpaper.If the langka removes the xs paint what is the point of using the sandpaper?
I've used the 2000 for my chips but am always afraid of taking off paint from the surrounding area so I usually tape the adjoining area.
Would you be kind enough to outline step by step your procedure?

You can touch up a chip fairly well with a pint of paint color matched to your original code by utilizing Langka and 2000 grit sandpaper, it takes time and patience, you finish with 3m rubbing compound.
If the hood has a small ding in the metal you can try and fill it with many layers of paint applied with a tooth pick but its extremely hard to get it perfect.
The other alternatives are the Dent Pro guys that specialize in small area touch-ups, I had it done on my previous 911 and it came out perfect and cost around $300.00
I had just a few chips on my 328 but many small pin chips in the front hood area and contacted a local Porsche dealer and asked the used car manager who they use and he told me the spot touch-up jobs dont last more than a year and reccomended a shop that does full paint repairs on exotics so they repainted my front section as well as my rear lid etc, it cost me around $2300, they did a perfect job and it will last, the touch up jobs can make it look better but I am pretty anal about chips and I would see any imperfection when I looked at that section of the car, so its worth it to me to have it fixed right and spend the $500-$600 to have your hood repainted

You're lucky it's on the hood. It can easily be removed from the vehicle and resprayed by itself. A good body shop should be able to remove the dent without using much, if any, filler.

My 550 suffered a pretty large stone chip on the hood today. I didn't even hear or see it at the time but the stone hit hard enough to cause a small dent with a full thickness chip of approximately 2cm in diameter. Beyond just touching it up, which will likely not be satisfactory given the size of the chip, does anyone have suggestions? I would really like to avoid having that area of the hood repainted but looking at that size chip every day will drive me nuts! Thanks for any advice.
