repairing chips on cast-iron/enamel sink

I have a Kohler cast iron / porcelain kitchen sink that suits our purposes and is in decent shape, except for significant chipping on a few of the edges where the sink rests on the countertop. The sink looks like crap where it is chipped, but we’d rather not replace it if the chips can be repaired easily. any suggestions? I was considering mixing some pigment in epoxy, but I think there has to be some commercially available stuff fir this very purpose.
Thanks.

There are little bottles of touch-up "paint" (almost like what is used for car paint touch-ups) available--maybe at hardware stores? Stores that sell stoves may also have it. You may also try contacting Kohler--they may have it or be able to tell you where to get it. Epoxy would be good if you could match the color. One of those companies that re-coat bathtubs may also be able to help you out with touch-up epoxy. Lastly, perhaps even the touch-up stuff used for dings in laminate couter tops may work.
would the touch-up stuff also work on a fine "spider web" kind of crack? no chips missing just very fine cracks where a heavy glass bottle fell into the sink. already replaced this sink once because of the exact same thing and don't wnat to pay for a third one.i don't think the sink is cast iron,its a pedestal sink and it wasn't that heavy when i put it in.
We have a local (KC) company called Surface Specialists that did a tub repair for a friend of mine and it's invisible. I knew where to look and I couldn't find the repaired spot. Maybe there's someone in your area with the same expertise.I've used the appliance paint and would not recommend it for spider web cracks. No way would it work. I would guess sink replacement is in order.

I'll check into a tub re-surfacing place, but I'm thinking it probably won't be worth the price. As far as the touch-up stuff,I think you're probably right.
Thanks for the advice.Maybe I'll just leave the cracked one ,since some one didn't listen to me the first time and insisted on keeping heavy glass vitamin bottles in the medicine cabinet above. :)
I agree with RCovell--filler probably wouldn't work on cracks; not enough width to get in there and bond.
Thats what I was afraid of. Thanks
The only time Ive seen this done it looks like sh^t .
The edging can never be matched and it never matches color.
Sinks that have a chipped edge can be bought for around 50 bucks from suppliers. Check around all the box stores by calling and ask for one as well at wholesale plumbing warehouses. Those are like new every where else and mebbe you can find one with the back damaged .
Otherwise its time to dig deep and buy the queen a new sink. Its been heard they might do extra favors for such jobs done complete.
