Just brushed, scraped, hot scraped, and then slapped on several layers of wax, things were fine. But then they'd looked nice and glossy before I started. I always do a lot of prep in October anyway (tomorrow!).I did that religiously for years. Then one year I didn't. It made no difference. My skis are regularly waxed so they had plenty of wax in the bases that 7 months of hanging in my garage did no damage to the bases or the edges.
