For those who want to use enamel, but have less odor, there is a type of low odor paint thinner available at art and craft stores.
I have not tried it myself, but I have friends who use it. I would have to experiment to confirm it does not have any bad characteristics with the hobby enamel I use, and more importantly to me, it is considerably more expensive than mineral spirits. I see it in pints at craft stores, but I buy my turpentine/mineral spirits in gallon cans.
