Randy, it's the tools you are using that's making it tough. You want to use really high-quality sharp scrapers, and let the tool do the work. Of course you still have to apply pressure to them, but not an excessive amount.
The best ones that I have found over the years are from Sweden, either Sanviks or another brand that I can't remember. (Tools are at the job). Take a look at these, you would have to be careful w/ them. Especially in the crevices. Plastic scrapers are not nearly aggressive enough, use the sharp ones and just make sure to go w/ the grain and take it easy at first. The cool thing is that the best scrapers in the world only cost double what a cheap one costs. Good luck w/ it!
Here is a link to good scrapers, just google Swedish carbide paint scrapers for more:
