I have also gotten white spots from scraping, but I was able to scrape them out. It happened from the heat from friction of scraping and it kind of mushed and smeared the day old cured epoxy. I waited one more day and it scraped out.

The scraper itself would get very hot (almost too hot to hold on to) from agressive scraping.
