I switched to shaped skis last year after skiing straight skis forever, and have noticed that after skiing the edge of my bases - say 1/2" to 1" on each side looks grey instead of black like the rest of the base. Is this somewhat normal because with the shaped skis I'm truly carving more? Or is this a sign that my daily wax isn't durable enough or that I need a full hot wax more frequently? Or is it an indication that I need a full base tune?
I've been using Swix F4 paste wax on my skis for 20+ years in between hot waxes. While I'm still having good results - nice, fast glide is there something more durable I should consider?
I typically ski 6-10 days a season at most due to living in MN, 90 miles to closest 250' vert hill, kids schedules, etc. so haven't invested in my own tuning/hot waxing equipment. I typically get a full tune/hot wax once a year and then apply a fresh coat of paste each time I ski.
While I'm happy with the speed of the paste wax I'm currently using, I want to make sure I'm properly protecting my bases as well. So what do you recommend?
