I also read where you experienced a wrinkle paint "failure" on a model. With regard to the paint failure, due to wrinkling upon applying additional coats, this issue/problem is easy to avoid. I addressed it in my Guide but it's important enough to mention again here. Every manufacturer will list very important time windows for re-coating on the label of the can. Not reading and adhering strictly to the time windows is what leads to this failure. I photographed a random spray can of paint and this manufacturer even highlights the instructions in bold type: "Any re-coating should be done within 3 hours, or after 72 hours." That means you have up to 3 hours to place additional coats on the model. After that window expires, you must wait a full 72 hours before applying any additional coats or the wrinkle paint failure can occur.
I have seen re-coat windows as small as one hour and then as long as five days before you can apply any additional coats. The thing to remember is that each manufacturer's formula is different and that will give you a different time window for initial re-coats and another different time window for re-coats once the initial window has expired. So, you have to read the label on every can you use.
Further along I read a reference to Marty's (of YouTube fame) method of removing wheels from the axles. I don't know why he uses a large sanding sleeve on a rubber mandrel. It's too large for accurate use, the steel wears out the sanding sleeves quickly and it just seems like a recipe for disaster. I use a small diamond de-burring bit. It's very easy to control and small enough so as not to cause collateral damage if things get out of control. The diamond de-burring bit lasts a long time and is inexpensive, the one I use is about the same size (or slightly larger) than the axle. I will sometimes use a smaller bit if I need more precise control.
