My favourite backcountry ski area has a really long approach along a groomed trail. I started putting a bit of kick wax on the base of my skis so I could make better time on the flat instead of skinning in to the base of the mountain. It works great, and I don't notice any loss of speed on the downhill (not that I go very fast in tight trees). I thought I was pretty brilliant until a guide told me that it ruins the base of my skis. Is this true? I would imagine that the solvent used to remove the wax would ruin my bases, but I don't use that much wax and usually just ski it off instead of using the solvent. Am I going to ruin my bases?
Yup works fine, not as effective without the wax pocket...but way faster than a skin slog...maybe 70% of a great wax job on classic skies.
Skins are not damaged by kick wax....I used skins and nordic skies for a decade back in the eighties...no problems.
Just use the right temp kick wax and apply exactly like a nordic job....
Downhill is not affected unless your wax job starts ti ice....the scrape off.
I think it's good to have first a normal wax as base on you skis and on top of that you can add the sticky wax. So you don't ruin your skis. But it's also good to remove the sticky wax if not needed and have faster skis.
And this don't work well if you have climbing skins :)
