Unless you have a rattle can that is a two part catalysed paint, (We won't talk about those in this discussion.) they all cure by out-gassing the solvents that make the paint fluid enough for spraying/atomizing. This leaves a layer of "solids" behind that we see as a painted surface.
Drying paint does so from the outside in. The film can be thin and dry to touch on the outside yet be uncured inside. It is still out-gassing through the thin outer "dry" layer and does so ever more slowly as the paint dries than as the outer layer gets thicker, making it more difficult to release the innermost solvents. The thicker the paint , the longer the process takes. The out-gassing process is accelerated with heat. This reduces the time for a more complete solidifying of the paint layers, as the solvents become more volatile and apt to migrate through the outer layers of drying paint.
Fuel is a solvent. So, if you soften that outer layer while the inner still has trapped solvents, large amounts of paint can be wiped off in panic. So, don't panic and wipe off spilled gas. Let it evaporate and allow the paint to re-harden. (assumes an advanced state of paint "dryness".
Still, some paint "solids" are less apt to suspend in a gasoline solvent than others. The EPA is on a mission to deprive the average consumer of any solvent that is very aggressive. (These can travel through skin and alveoli more readily and put toxins into the bloodstream). Paint blended with very aggressive solvents, is much tougher after the cure than those with weak solvents, because it takes aggressive solvents to suspend these solids. Many modern rattle can paints are blended with mild solvents. And, this makes the solidified paint more easily attacked by whatever solvents it comes in contact with, after the cure.
Using a kitchen oven that will later be used for food, is blatantly stupid and irresponsible. The out-gassed paint solvents deposit onto oven walls, and later become incorporated into the food prepared in there. If you wish to ingest these known carcinogens, make that decision for yourself. But, don't foist your decision onto those around you without their expressed agreement. If you wish to poison or induce cancer in those you reside with, then don't expect any sympathy or remorse from others when you are found with a hatchet lodged in your forehead. I would accept the self defense plea as justified, from the hatchet wielder.
I rattle canned a full sized airplane many years ago in a beautiful Metallic Blue. Few believed it was done in such a way by the look of the finished product. It really looked great for about 6 Months. After that, the California sun began breaking down the solid binders. It began to chalk and a year later you could literally wipe the paint off as a blue powder in all but the places where the the sun couldn't reach. This was rattle can paint I found in auto stores intended for touch ups. If I had kept the plane in a hangar out of the sun, I expect it would still be beautiful to this day. I don't know of any auto touch up rattle can paints that have the UV blockers needed to withstand the sun and elements for any length of time.
Terry's 2 part catalyzed clear coat is a good protecting outer layer for such paint. But, that wasn't from a rattle can, either. And, 2 part paints have personal safety issues that should be studied and addressed before implementation.
Cheers,
