Road Cycling “It is by riding a bicycle that you learn the contours of a country best, since you have to sweat up the hills and coast down them. Thus you remember them as they actually are, while in a motor car only a high hill impresses you, and you have no such accurate remembrance of country you have driven through as you gain by riding a bicycle.” -- Ernest Hemingway

Touch-up Paint?

I have a tiny paint chip on my bike's chainstay that bothers me.

What's the best way to make it go away? I've heard nail polish, paint pens, touch-up pens, etc., but dunno if I want to risk doing that to my bike and making it look worse possibly. I'm not sure the paint color is pure white either.

It's inside the 0 of the 10 on the chainstay, chip in the white reveals red paint beneath it.

Nothing will be perfect, but your best bet will be matching auto touch up paint at an auto parts store. They don't usually mind you bringing your bike into the store. They have a wide range of colors in small applicator bottles.

Put a "1" in red after the chip (in other words, "10.1"). People will think you have a special CAAD10.

Nah, seriously, if the chip is clean (no rough edges), just clean it with rubbing alcohol, and put a little clear nail polish over it. Even with a perfect paint match, it will likely stand out. You will likely get far worse than that chip over time - but I understand trying to keep things looking pristine.

mask it off and use nail polish, if you take your time it will come out just fine. If you would rather have C'dale paint try Cannondaleexperts.

I contacted them and they told me Cannondale hasn't made touch-up paint since 2006!

A little nail polish will pass unless closely inspected and take the nut off the tube stem.

Off the web, can't find the link:

Colnago painting UPDATE: My thanks to Bruce Thompson for the following advice:


I concur with the last person who posted a comment about the softness of the Testors paint. In that it may look fine to photograph a bike that sits indoors, it can never stand up to abrasion or weather, not to mention a good past wax. I am not satisfied if a touch-up can be detected from 6 inches away, much less 6 feet.
I first prep the chip by deciding if there is rust in the pit or not. Also if there is loose or chipped paint I will remove it with a small needle file. With a toothpick I will dab a drop of Naval Jelly just big enough to fill the chip hole. It is important not to let the Naval Jelly to run on the rest of the painted frame. I fill several chip holes at the same time and wait at least half an hour and then wipe the area(s) off with a wet rag. If you became friends with an auto body shop, you could secure a small bottle of epoxy primer and catalyst. I was fortunate enough to find a can of each at a yard sale...enough for 30 years of filling in scrapes and stone chips. I will mix the catalyst and the resin a couple of drops at a time on the lid of a paint can and again apply the primer with a clean toothpick. Wait about a half hour for it to dry.
The paint products I prefer are from the automotive paint company "Dupli-Color" Although they don't have every color under the sun, their products are LACQUER and the lacquer works better, dries faster, shapes, sands, and polishes better than anything else I have found. I always have a bit of lacquer thinner on hand when I work the touch ups. If the chips are excessively wide or very deep, you must also make the determination of using a 'spot putty', also available at auto supply houses. This stuff is thick and goes over a primer then should be primered AFTER it is sanded smooth.
I fill a small metal cup with the lacquer and slightly thin it, filling up an artists brush till its full. We are not just painting to cover the chip but filling the void. So I give a slight push to the brush and draw it out slowly watching for the 'dome' to show on the filled hole. Lacquer can dry in as little as 10 minutes so there is a chance to do several chips in a single pass. One of the methods I use to level the new paint is to have those flat wooden swizzle strips that better coffee shops have on hand. I usually make about a dozen disappear on a visit. When I get home, I will sand the ends smooth and then super glue 320, 400, and 600 grit strips to the ends. This is what takes off the rounded dome of the chip. If the paint is not 'proud' you will have to do it again. Successive sanding is followed by using the nail buffers that your wife has. If you are certain of your masculinity, you can go to a beauticians supply and pick ups a small pile. The grit of these abrasives are not specified, but will be down to about 1000 grit if you chose right. One one side there is usually a 'buffing' or polishing side without abrasive. This is the final step. Buff out any of the course grit marks and then stand back and admire the work. You then may apply a thin coat of clear if you wish. I just finished a GRANDIS that looked like it was rolled down a cliff and is now almost show-room quality. You can't tell where the chips were from 3 inches.

Ride more.

After you get a bunch more nicks, scratches, and chips, it will be very difficult to even see this.

I wouldn't worry about it. It'll keep coming off until you stop hitting the chainstay with your heel.

das good


FPS David, I would honestly ignore it, you are only going to get more and it will drive you crazy, Jseis seems to have the best method, testors model paint is crap, nail polish is better.

But its a lot of chemicals and preparation for a menial mark.
