How long does it take for oil to cure on a rattle can?

The main problem is in using a rattle can. Many brands will get the wrinkle problem. In a rattle can, there is much more solvent to reduce the paint. If the solvents from the previous layer haven't completely released, the next coat will melt the coat below it. Also, oil/alkyd can take up to 30 days to fully cure. I prefer uerathane whenever possible. It is best to do all coats within an hour of each other, or if you do wait 24+ hours, do a couple light coats first and then do your final wet coat. The best way to get good results though is to ditch the rattle can and use an hvlp spray gun. You can get a setup at Harbor Freight for very inexpensive. You will save on paint for all future projects as well, as rattle cans are more expensive for the actual amount of paint you get in them. Hope this helps someone.
