Quote: Are you using 100% mineral spirits or some paint thinner that contains some mineral spirits? whatever you use whether it's odor or odorless it should be 100% mineral spirits.
you say you soaked the roller then started. that's the problem if you ask me. you shouldn't be putting much paint on each coat. if that surface wasn't flat when you painted it (assuming it was) you would have runs instead of orange peel. Put it so the surface is vertical and try again with much less paint per coat. If you see runs, you're putting it on too thick. Once you see how much you need to put on (which is not much) you can do other surfaces.
100& mineral spirits? I am using paint thinner that contains mineral spirits. Does it really matter? How does one put paint on the roller then? Do I use the foam roller to brush it onto the roller?
I think it does really matter. That paint thinner can contain a bunch of other things that affect how it goes on, how fast it dries, so forth.
When you say you soak the roller that makes me think you are filling it up then taking it to the panel and laying down a nice thick layer of paint, which is what you want to avoid. I've only tried that on a decklid where I was going to quickly be able to spread all that paint around. It looks from your pic that your paint went on too thick and perhaps the thinner you used started drying before the mixture could level out (although it can only level so much if there's too much paint there). So after soaking the roller you would either use ALL that paint to do your area (tougher) or squeeze most of it out and do one area/portion at a time. I usually squeeze most of it out which leaves a nice thin layer that goes on super flat. For a big Dart hood I might go back to the paint tray 5 times..
