I did mine with circa 1850, and it worked. It was slow going though since it just turned the enamel and primer gummy rather than lifting it. You'll have to either remove or be really careful around rubber or plastic parts. It'll melt fiberglass before you know it!
That spray-on Aircraft remover (it's name) is pretty good stuff. Stays where you spray it. I used Aircraft remover, then removed it and the paint with a power washer. Still need some sanding, though.
