I have used every method of paint removal discussed thus far and IMO they all have their place.
When I stripped the stepside bed on my '65 I used Norton Rapid Strip Discs on my 4-1/2" angle grinder. They are available at Home Depot. I used 10 discs and as I recall they were about $9 each.
Like every other paint removal method it is a dirty job so plan on doing the work outside! I used a respirator and a full face shield and was covered with filth.... just sayin.

Hope this helps.
