I'm really resisting sanding and have been using naptha with a kitchen dish scrubber.
You might want to check places like AutoZone, Checker, Napa, etc... for some aircraft stripper (Methylene Chloride). That stuff made real easy work of stripping most of the original finish off
my Bachbird.
From what I garnered from folks here and at the refinishing forums, the chemical peel won't always work - but when it does the paint just blisters and gives way with gentle scraping. When it doesn't do the trick folks were having to sand and use heat guns to soften and scrape the epoxy paint off. The latter approach looked pretty treacherous, as you have to be careful with the heat to avoid causing damage.
You're making good progress! That and the finish sanding/polishing really took a lot of elbow grease.
