Paint baking
I remember my Grandpa painting parts for his (mine now) truck. Spray paint. He would then put them in the oven when Grandma wasn't home. Has anyone done this and if so, what temp and for how long? I understand powder coating cures this way, but I am interested in learning the old way. Thanks, Randy

I tried that years ago on some parts for a bike, to speed up the drying time. It did not seem to make a difference in the end result. The paint was not any more stronger than before I heated the pieces. Actually, it was more of a hassle and mess than anything. I tried to take the piece out of the oven while it was still cooling down so the paint was real easy to smear and mess up. I used rattle can paints. I wouldn't recommend doing that if I were you. If you're going to paint something with quality automotive paint you will mix a hardener and a base color to create a very very hard and durable finish. I did that on my antique boat last summer and the finish still looks great. Powder coating is the only application that I would use an oven to cure for. But I have not been around as long as some of the others here, so maybe others can give you different feedback.

I believe baking paint is to speed cure time. But rattle can paint doesn't cure, it dries. Popping it in the oven will start to break down the paint, reducing its durability, or melt it if its hot enough. Its best to put the part in a warm room or near a warm vent. You only need to help evaporate the solvents out.
2 part auto paints are a chemical cure, kinda like Epoxy. "Baking" them in an oven adds energy to help drive the reaction faster causing it to "kick off" sooner. Also, the oven is only 170 degrees or so.
Ofcourse, I'm sure there are exceptions
