Removing the old paint “edges”

So, given the very spirit of why I shared and sought advise, I don’t want to mask todays problem just to create more work down the road. So I am thinking I take this as a lesson learned, and “it looked good before, but will look really good next time” and move on.

That said, what is the best way to get it peeled back down to the appropriate level and start over? There’s no way I can strip every nook and cranny like it should be, not by hand. I don’t see anyway other than blasting it. But, I don’t want warping problems either. Best way to go at getting it off?
