I don't know the answer to your question, but I am fairly certain that were you to find someone who does re-enamel appliances, it would be quite expensive.

You may want to check with people who refurbish antique ranges.

Call or drop by a body shop. They don't do appliances but may know who does.

Refinishing porcelain is prohibitively expensive (it can't be painted). Painting non-porcelain can be reasonable. Check with your local high school, sometimes the auto-mechanics class needs/takes outside projects and your cost may be only the paint. Auto-body shops may also take jobs but of course can be $$$ ... unless you know someone on the inside.

They would have to be painted in place, if anyone out there has heard of this being done, I would be surprised. Do what Sophie suggested.

There is no way you could paint in place. For actual enamel and for powder coating, you have to bake the porcelain. That has to happen in an oven. For automotive paint, you still need to heat-cure the clearcoat, but you might just be able to get away without actually placing it in an oven. You need to either do an amazing job masking the appliance though, or you need to place the individual component into a spray booth. Overspray is difficult to manage otherwise.

In other words, you are almost certainly going to disassemble your appliance and will then refinish panels separately. For some appliances this could be easy to do; for others it could be prohibitively difficult. Essentially, if you appliance was "panel ready", then this is easy. But if it is panel ready, then why don't you just buy a new panel instead?

I don't want to rule out that there are options to refinish minor blemishes without going to all this trouble. I am sure somebody has invented a touch-up solution that uses colored resin. But it'll never be as resilient a finish as what you'd normally expect on a kitchen appliance.

Heck, for that matter, automotive paint isn't even going to be anywhere as resilient as true enamel. I don't think you could use it on a stove. It just won't stand up to those temperatures very well.

Mind telling us some more details? Maybe it is an appliance that still has spare parts? Or you can buy a broken one that you can break done for parts?

Thank you all for your varied and valuable input. Rita, thanks for suggesting an antiques refurbisher. When my dishwasher and refrigerator died, I could not find replacements in bisque that have modern features so I bought them in stainless. The range is a 23 year old GE XL44 that is in great condition. The oven temp is right on target, and it has one high intensity and one low intensity burner. It has some chipping on the long enamel panels, grates, and discs that sit over the burners, but it has functioned without the slightest glitch. New grates and discs are not available. The knobs pull right off. A professional/chef friend who owns a fabulous, expensive oven has had problems and told me not to replace mine, as have others who have bought new ranges. It's a slide in. The warming drawer and door, which has a glass panel over it so I can peek inside during baking , are likely removable. I had no intention of doing the work myself in my home, as I live in an apartment building and do not have the space or expertise. Here are a few pics. (Apologies for the grates, which need a cleaning.)

The good news is that you can probably remove all these parts and mail them in to have them refinished.

The bad news is that these are all parts that get hot enough you really don't want anything other than a full re-coating in proper enamel. A patch job is never going to work well.

A quick web search finds that there definitely are places that can strip the old enamel and put new enamel on. But this will be quite expensive. I'd give these people a call and ask for advice: http://antiquegasstoves.com/

My suspicion is that for the cost of a properly done repair, you can easily buy a brand new and high-quality stove. This forum will be able to provide recommendations for brands that are reputable and are known to build high-quality appliances.

You'll almost certainly get a better result this way. But if you are emotionally attached to your stove, that a perfectly fine justification to refurbish it. Even if it costs you a pretty penny.

Or you could face the reality that all of these are simply minor cosmetic blemishes and ignore them for the next 10 years. If the knobs need replacing, that's probably an easy fix, though.

Basic GE ranges remain high in CR ranking every year. You need not fear replacingbiy. And it will be one third the cost of attempting any refurbishment.

Thanks again, Sophie. I appreciate your candid response and will seriously consider your recommendation.
