Paint peeling I have a GE Space Saver it is peeling in the back corner it will spark if the rack is in. If I use the microwave without the rack it is fine. Is there a paint I can use to fix it?

Pry off plastic tab. Clean up burn marks with sand paper and touchup paint. Order a new rack clip. Also clean any burn residue off rack.
MOST IMPORTANT: After the repair, do not put the rack back in unless you are cooking on it. Running the microwave with nothing on the rack is what causes this to happen.

follow this steps and fix it. God bless you

Waveguide Cover

If the microwave is sparking or arcing the waveguide cover might be damaged and shorting out. Try removing the waveguide cover and see if the problem goes away. If there are any damaged spots in the microwave ceiling or sidewalls, repair them and paint them with microwave oven paint. Replace the waveguide cover if it is burnt or if it will not stay in place.

Microwave Oven Paint

If the microwave is sparking or arcing on the side walls the paint might have chipped causing pitting in the metal oven wall. Use microwave safe paint to touch up any bare metal spots.

Rack Support

If the microwave is sparking or arcing near one of the rack supports, remove the support, repaint any bare metal, install a new support.

This has to be grease, food debris, or carbon, probably on the rotating rack.

Run the oven for a few seconds empty - with and without the rack - to find where it is arcing.

Then clean, sand, and repaint with high temperature appliance spray paint as needed.

Very difficult to explain briefly as microwaves are truly complex.
You will almost certainly have 2 problems. 1)You need to carefully sandpaper the area where the paint is peeling off and "only paint with appliance paint as this does not have lead in it and 2)The sparks are due to a variety of things, but the most obvious, replace your main capacitor and HV diode. This combination is the normal culprit for arching. If it continues after that, the Magnatron needs replacement as well (Unfortunately, for first time diagnosis, electrical testing equiptment is needed.)

THERE SHOULD NOT BE ANY METALS IN A MICROWAVE WHEN THE UNIT IS RUNNING
If the unit paint is flaking and behind that flake is metal.. You need to throw it away or talk to your appliance guy and see if there is a speacial paint to coat the metal so you can use your MW

Here is a link to buy the paint.
If the microwave is not creating a spark inside when in use, It's OK to use.

The only real danger is if it continues, it can deteriorate the metal, allowing sparking and possible leakage.

It's a good idea to clean, sand, clean again and repaint the area.

High temperature appliance paint is available form stores like Lowe's and Wal-Mart.

You need to thoroughly clean it, then sand it smooth to removew all the loose paint.

Once it's squeaky clean and dry, you can apply high-temperature appliance paint, which is available in brush-on or spray-on form at big box stores like Wal-Mart, home improvement centers like Lowe's and appliance parts stores.

Normally you can strip and sand the old paint, get it squeaky clean, and use appliance paint. Yes indeed it is a heat-resistant enamel. You can get it from appliance parts stores, Wal-Mart, or home centers, etc. BUT if it's under warranty I would call GE Customer Relations with your model and serial numbers. They're at 1-800-386-1215 (8-6 ET) and I would also suggest you ask them for a referral to a GE-authorized servide center in your area. Good luck. I appreciate your thoughtful rating of this answer.
