Paint for a Porcelain Stove?

I recently picked up a Chappee 8803 wood/coal stove in excellent condition for a song.. Excellent, except for the brown porcelain/vitreous finish. There are no chips but the entire surface of those parts that receive a lot of heat are "crazed" giving them the appearance of gray/white mold. It's not mold. I've tried using scoring powder, acetone, wet sanding, vinegar, baking soda and rubbing compound to no avail, although some of the remedies seem to work only to return to the dull finish when dry. It seems now that the surfaces have a billion microscopic cracks giving the look of being covered with dull gray powder. The only inexpensive way to brighten the stove up may be to paint it. Will Stove Bright paint adhere to the "glass" surface? What surface preparation is needed? Etching the surface first- with what?
Has anyone else had this problem and found a solution?

I have a Chappee with a similar but possibly not as severe condition. That gray discoloration spoils the entire look of the stove. I have tried everything I could think of also with the same result that you got....zip. I believe it was a defective initial process that caused this discoloration since none of my other porcelinized stoves suffer from it. I thought about powder coating it but never pursued it. I am anxious to hear if anyone ever solved this issue. Mike

I suspect if you have used abrasives or sanded with anything that was coarser the 0000 grit the show may be over. I would call a company that refinishes porcelain tubs and sinks for some advice.

If you want to restore it's original finish as mentioned, you will have to contact a specialty outfit but if a clean new finish regardless of originality is wanted a sandblast job would surely get the old stuff off. In fact a restoration of original finish might require the stove being reduced to bare metal.

If this is a circulator type stove the porcelain doesn't get all that hot.

If, as you say, it looks improved while wet until it dries, why not try a clear coat finish.
A single spray bomb is not going to cost you a lot to find out

McGiever, You may have found the solution! After an hour of applying a coat of Rustoleum Hi temp clear the grey dusty appearance has not returned. With the other remedies, the moldy appearance reappeared within 20 minutes. I'll check it again in the morning. Thanks

Hi temp clear does the job!! The Chappee looks brand new. I guess the clear coating masks the oxidation and prevents its return. Thank you McGiever.
